# Tributyl phosphate manufacture from phosphorus oxychloride and n-butanol

## 1. Scope and Applicability

This method covers one chemically defined, unformulated technical-grade liquid product: tri-n-butyl phosphate (TBP), CAS126-73-8, C12H27O4P, manufactured by direct reaction of phosphorus oxychloride with n-butanol and separation of HCl, excess alcohol and actual process solvent. It covers the factory-gate product and its actual synthesis, purification, delivery and pollution-control operations. Feedstock manufacture is connected through compatible supplier datasets. WHO EHC112 sections2.1/3.1 establish the identity and conventional feed route; the producer product page independently confirms the product identity (`who-tbp-1991`, `lanxess-tbp-product`).

Include only actual direct-esterification configurations supported by the site flow sheet. US3079419A, figure1, description and example3 document an HCl/alcohol separation configuration including xylene reflux/recovery; it supports route decomposition, not a recommended contemporary recipe (`stauffer-trialkyl-1963`). Washing/residual neutralisation and abatement are included when actually installed and recorded. The OFC and CWW BREFs supply chemical-sector stream characterisation and recovery/treatment principles, with their applicability qualifications (`jrc-ofc-2006`, `jrc-cww-2016`).

Exclude inorganic phosphoric acid or phosphate salts, other alkyl/aryl phosphate species, acidic mono-/diester products and their salts, formulated plasticisers/antifoams/hydraulic fluids/extractant solutions, other inorganic-acid esters, organophosphorus pesticides, reclamation of contaminated extraction solvent, sodium-alkoxide phosphorylation, and end-use metal extraction or nuclear processing. A different product-use label alone does not create another TBP identity or prove an exclusive manufacture route or grade. The reference is the whole accepted commercial liquid, including measured residual constituents permitted by its lot specification; it is not pure-TBP equivalent. No source provides a universal dose, solvent content, yield, purity, energy intensity or emission factor.

| How much | 1 kg reference flow |
| How well | Actual lot acceptance for TBP identity, assay, residual water/alcohol/solvent, acid value and customer specification |
| How long or cycle | Factory-gate supply; declared campaign/production period, with storage losses measured |
| reference_flow_link | finished_tbp |

| Field | Value |

| Reference amount | 1 |
| Reference product flow | Tributyl phosphate `ed60d109-7ca7-424b-a634-1bf3ae4a8017` |

Declare every required qualifier in dataset metadata, process notes or reference-flow comments; missing qualifiers make that data package incomplete.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Use 1 kg accepted net as-supplied unformulated TBP, excluding packaging. Q is the measured accepted net product mass of the same campaign, collected by cp_product; assay is a qualifier, not a change of denominator. Q includes the accepted residual water, alcohol, solvent and other measured constituents; count each accepted factory-gate production lot once, reconcile dispatches and finished stocks, and exclude repeated internal reacceptance of the same returned material. |
| active_basis | all inventory rows | Mass | kg | Keep supplied chemical/solution mass, measured active mass and embedded water separate in the physical ledger. Product active TBP = product net mass times measured mass fraction; do not substitute this active mass for Q. |
| utility_basis | steam, natural_gas, nitrogen_input, tap_water, electricity | Native verified reference property | native unit | Preserve each native unit/property. Match meter, phase/grade and provider reference basis; conversions require traceable density, gas T/P/composition/Z or steam enthalpy with condensate basis. Unknown compatibility stays pending. |
| emission_basis | all elementary outputs | Mass or verified Volume | kg or m3 | Mass species/ion/element basis, fossil/biogenic origin, wet/dry gas conditions and compartment must agree. Never infer NO2-equivalent from a kg property or kg salt from kg chloride. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Traceable delivered POCl3/n-butanol/actual auxiliaries and utilities at plant receipt, with opening inventories and supplier origins/assays recorded |
| starting_condition_role | Foreground collection starts at received chemicals; their production/transport remain linked upstream burdens |
| product_classification_scope | TBP subset of CPC34180 only; no applicability by source database classification or similar phosphate names |
| recursive_input_rule | Same-category purchased TBP or externally reprocessed returns require explicit supplier identity/state and nonzero upstream dataset; internal recycle remains an equal-quantity stage link, not a new reference output |
| upstream_dataset_requirement | Every external product/waste/service interface needs a compatible supplier/receiver dataset and quantity basis; record open linkage when unavailable |
| disclosure | Disclose actual chemistry, utilities, abatement, starting stocks, campaign coverage, formula/assay, loops, receivers, allocation, exclusions and gaps |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_route | tbp_manufacture | Retain receipt, reaction, actual HCl recovery, neutralisation/washing, phase separation, alcohol/xylene recovery, purification, storage/filling, cooling/vacuum and waste/gas/water treatment in the process record. Record the actual order and measured stage flows; no historical recipe/temperature/yield is imposed. | stauffer-trialkyl-1963; jrc-ofc-2006 |
| boundary_loops | all stage links | Keep unallocated total mass, C/H/O/N/P/Cl/Na elemental stocks and a separate molecular-water stage ledger. Each internal transfer has identical sending/receiving mass and composition; count external make-up, bleed and losses once. | jrc-ofc-2006; jrc-cww-2016 |
| boundary_treatment | all emissions and wastes | Separate recovered product, off-site waste and direct residual release. A liquor sent off-site carries its measured waste composition and receiver treatment burdens, not an immediate freshwater elementary release. Include plant boiler/oxidiser/biological-treatment emissions when present, without duplicating purchased utility generation. | jrc-ofc-2006; jrc-cww-2016 |
| boundary_completeness | all inventory rows | The cards are an atomic baseline, not permission to omit actual exchanges. Extend the dataset with a separately named, measured and verified row for every additional actual auxiliary, coolant/refrigerant, packaging component, salt, organic species, waste, emission or destination; an unresolved identity is not zero. Document absence and cut-offs with measured relevance. | jrc-cww-2016 |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| tbp_manufacture | TBP manufacture and delivery | required | Declared actual direct-esterification route; abatement/packaging branches as recorded | foreground production | finished_tbp |

Receipt/stocks → n-butanol/POCl3 reaction → actual HCl separation and alcohol/xylene recovery → actual residual-acid neutralisation/washing and phase separation → purification/finishing → lot acceptance/storage/delivery. Vents, washing liquor, bottoms and other actual residues connect to their treatment/receiving branches in the actual site order; retain separate stage meters, samples and equal-quantity internal links. The aggregate foreground unit has one final reference output; internal crude/purified ester is not another factory-gate reference product.

###### Sodium hydroxide solution, 30% (`sodium_hydroxide`)

Conditional on actual nominal 30% aqueous NaOH receipts for residual-acid washing or scrubbing. The native reference is whole supplied solution mass. Record actual NaOH assay, carrier water and all residual constituents; the nominal label does not establish a default water fraction. Embedded water is not counted again as purchased water. No default dose follows from 30%.

- Selected flow: Sodium hydroxide solution, 30% `7115909b-796c-4b3d-b40a-1a7c693d12d0`
- Flow property / unit: Mass `93a60a56-a3c8-11da-a746-0800200b9a66`; unit group `93a60a57-a4c8-11da-a746-0800200c9a66` / kg

###### Nitrogen gas (`nitrogen_input`)

Conditional gaseous N2 for actual TBP inerting/headspace or equipment blanketing, with actual air-separation supplier origin, grade, phase and provider basis confirmed. The native at-plant inerting/headspace context and Mass/kg reference match this role; its bottling-use wording does not establish exclusive manufacture or grade. Measure gross external fresh gas mass by stage and reconcile internal transfers, retained gas and actual vents. Descriptive make-up/vent wording supplies no quantity or fraction. Volume-to-mass conversion needs actual T/P, composition and compressibility; no fixed density or unsupported reference normalization.

###### Treated tap water (`tap_water`)

Meter treated supplied water for washing, HCl absorption, cooling make-up, boiler make-up and cleaning separately in stage records. Collect supplied volume in m3 and actual geography/provider. A geographically restricted water identity cannot serve an unverified site. Retain this concrete exchange without a UUID until the actual supply and reference-volume basis match; use measured density/composition for the mass ledger.

###### natural gas in the gaseous state (`natural_gas`)

Conditional on an on-site gas boiler or thermal oxidiser. Reference Volume/m3 requires meter T/P, dry/wet composition, Z and provider volume convention. Secondary Mass factors are not density. Do not count purchased steam generation again.

- Selected flow: natural gas in the gaseous state `4f19ca0e-7b3b-11dd-ad8b-0800200c9a66`

###### Empty HDPE drum (`hdpe_drum`)

Conditional packaged delivery; weigh the purchased complete drum SKU with its supplied closure, exclude product contents, and retain reuse cycles/cleaning records. Resin and generic packing are not the converted drum. When a provider delivers a complete container, its measured reference includes the supplied closure/components; do not add their manufacture again. A handling, cleaning, reconditioning or reuse service is a distinct burden with its own provider/reference unit and actual number of services or cycles, not the full-container mass. Preserve separately purchased actual components as atomic exchanges only when not included in the complete-container provider. Bulk delivery records absence.

###### phosphorus, total (`total_p_water`)

Total-P analysis closes the phosphorus ledger. Where named P species are inventoried, this exchange can carry only measured remaining P after subtraction of their kg-P equivalents, with the residual composition and LCIA compatibility reviewed; otherwise quantity linkage stays pending. Never sum total P and all its constituent P again or hide toxic organophosphates in the sum. Only direct release to fresh water after on-site treatment; other destinations need their exact atomic identities.

## 7. Allocation and Co-product Handling

Declare the study goal and attributional modelling context before using the following shared-burden rules. System expansion/substitution requires a separately justified scenario consistent with the study goal; it is not interchangeable with allocation or an automatic recovered-product credit (`jrc-ilcd-2010`).

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_subdivide | environmental burdens | Avoid shared-burden allocation through measured stage subdivision where feasible; retain separate common utilities and treatment records. Identify actual independently accepted HCl/recovered alcohol co-products before any allocation. | jrc-ilcd-2010 |
| allocation_basis | remaining shared burdens | Use a documented physical causal relationship where supported; otherwise declare a justified alternative such as contemporaneous net-sales economic shares with source, period and sensitivity. Do not apply a fixed default share or assume every byproduct sale. | jrc-ilcd-2010 |
| allocation_physical | all physical outputs | Allocation changes attributed burdens, never measured product, co-product, waste or emission quantities in the unallocated process/total-mass/C/H/O/N/P/Cl/Na/water ledger. Keep physical and attributed-burden accounts separately reconciled. Avoid crediting internal recycle or waste twice; any substitution must disclose its expanded-system basis and remain an explicit separate scenario. | jrc-ilcd-2010 |

WHO environmental GC methods inform analyte identity/blank control, not a product purity limit. Aggregation detail: Sum whole accepted commercial net TBP Q without packaging, including measured allowed residual constituents; count production acceptance once and reconcile dispatch/finished stocks/returns; record co-product masses unallocated; normalize exchanges per 1 kg reference flow | kg | every lot and each dispatch | complete declared campaign with representative starts/stops | same site and actual suppliers/receivers | per 1 kg reference flow | scale calibration; lab validation/blanks/recovery; buyer acceptance |
| cp_material | tbp_manufacture | atomic external feed and packaging | receipt, assay and stock records | supplier/grade/CAS; source route/carbon origin; solution mass; active assay; water; solvent/isomers; inventory changes; drum SKU/net mass; returns | Weigh each actual material lot and reconcile opening/closing tanks; use supplier certificates verified by site sampling where material; retain supplied solution and active/carrier ledgers separately.

| cp_utilities | tbp_manufacture | one atomic utility at a time | meter and supplier records | stage/time; kWh/MJ; water m3/density; gas m3/T/P/Z/dry-wet composition; nitrogen mass; steam kg/0.45MPaG/T/dryness; condensate kg/T; feedwater and provider basis | Read calibrated meters at receipt and stage boundaries; reconcile common-meter allocation with timed operation. Record native reference bases and independently establish each provider/conversion compatibility. Aggregation detail: Measured attributable utility in its native unit per 1 kg reference flow | native unit | continuous or each batch/meter interval | complete same campaign including idle/start-up and treatment | same site and actual suppliers/receivers | per 1 kg reference flow | calibration; logs; supplier basis; gas analysis; enthalpy records |

Validate specific organic, ion and total-P analyses with digestion/speciation definitions and blanks; wastewater sent off-site stays a separate waste interface. Aggregation detail: Actual final species load and liquid-water quantity per 1 kg reference flow; totalP analytical ledger reconciled separately | kg or verified m3 | each discharge interval and representative batch composite | same campaign; temporal sampling reflects variable emissions | same site and actual suppliers/receivers | per 1 kg reference flow | methods/standards; blanks/recoveries; flow meter; receiver/outlet coordinates |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| campaign_basis | all inventory rows | a_i = A_i / Q; A_i is the measured stock-corrected external exchange for the declared campaign in its native unit; Q is accepted net as-supplied TBP mass in kg. Reference output is 1 kg. | A_i; Q; cp_product; relevant row protocol | a_i |  |
| assay_ledger | solution and product composition | Active mass = supplied net mass × measured active mass fraction; carrier water and other constituents come from actual composition. Sum constituent masses without adding them as additional duplicate purchased exchanges. | cp_material; cp_product; measured fractions | active/carrier composition ledger |  |
| reaction_ledger | reaction and neutralisation | Ideal substitution identity: POCl3 + 3 C4H10O -> C12H27O4P + 3 HCl. It produces no esterification water. Actual neutralisation HCl + NaOH -> NaCl + H2O generates water; POCl3/ester hydrolysis consumes water and must follow measured species. These equations check atom accounting, not actual feed ratios/yields; record residual alkali, acid, salts and incomplete esters. | cp_balance; cp_material; cp_product; actual speciation | reaction/neutralisation P/C/water/Cl/Na ledger | who-tbp-1991; stauffer-trialkyl-1963 |
| physical_balance | each stage and plant | For mass and each conserved element E: opening stock + external input + internal received = closing stock + external output + internal sent + documented residual. Internal sent/received cancel only when both ends match. Only the molecular-water species ledger adds actual reaction formation and subtracts consumption; total mass and conserved elements have no reaction-generation term. Include water in solutions/steam, inlet humidity, wet air, condensate, product/waste moisture and outlet vapour, and include measured purge/vent carrier and combustion oxygen. Reconcile energy with electrical work, fuel calorific basis, reaction/sensible/latent enthalpy, steam/condensate, cooling, losses and stock changes in a separate energy ledger; kg and MJ are not additive. No guessed closure factor. | cp_balance; all actual composition/stock records | unallocated total-mass/C/H/O/N/P/Cl/Na and separate molecular-water/energy residuals | jrc-ofc-2006; jrc-cww-2016; jrc-ilcd-2010 |
| emission_load | all elementary outputs | Load = sum of paired concentration × compatible gas/water flow × duration, converted with recorded units; apply actual inlet correction where appropriate. Distinguish wet/dry and reference T/P/O2; non-detects keep bounds and cannot become automatic zero. Independently reconcile diffuse losses. | cp_air; cp_water; calibration and time series | actual net species load | jrc-ofc-2006; jrc-cww-2016 |
| phosphorus_partition | total_p_water and named P species | Keep totalP as an analytical closure value. Residual P = measured totalP minus P equivalents of individually quantified species in the same outlet/time window. Use actual stoichiometric composition for equivalents; forbid negative residuals or duplicate totalP/species loads. Residual composition/LCIA basis remains pending until substantiated. | cp_water; actual species composition | disjoint named-P and residual-P accounting | jrc-cww-2016 |
| yield_recovery | reaction and separation | Derive actual yield from accepted TBP assay mass and actual limiting-reactant/speciation records, accounting for recycle stocks and co-products; derive recovery from measured sent/recovered/bleed quantities. No patent laboratory yield or solvent ratio is imported. | cp_material; cp_product; cp_balance | site-specific yield and recovery checks |  |
| burden_account | allocated environmental burdens | Apply the justified allocation shares only to the remaining shared burdens after subdivision. Preserve all physical outputs and emissions in the unallocated ledger and retain the separate attributed accounts and reconciliation. | measured stages; justified shares; physical ledger | attributed burden accounts | jrc-ilcd-2010 |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| dq_trace | all inventory rows | Trace each row identity, measurement, unit/basis, supplier/receiver and required qualifiers; preserve every open linkage | row records and original calibration/analysis |
| dq_coverage | tbp_manufacture | Same period/product mix; cover starts/stops, downtime, returns, waste stocks and material peaks, and disclose representativeness gaps | production/meter time series |
| dq_uncertainty | balances and emissions | Review residuals using actual method detection limits, sampling error, calibration and composition uncertainty; no invented survey coverage, universal tolerance or unmeasured zero emissions | uncertainty and residual investigation |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validate_identity | reference product | Require actual TBP CAS126-73-8, direct POCl3/n-butanol route, unformulated market state and complete lot qualifiers. Similar phosphate/salt labels and source classification do not establish identity. | who-tbp-1991; lanxess-tbp-product |
| validate_measurement | all inventory rows | Require one finished reference output at 1 kg, the same Q denominator in inventory and collection, and native reference-property/unit compatibility. Missing gas/steam/concentration/provider basis remains explicitly incomplete. |  |
| validate_balance | all stages | Reconcile total mass, C by origin, H, O, N, P, Cl and Na stocks, molecular-water formation/consumption, wet-air/purge/vent carriers, neutralisation salts/residuals and stock changes before allocation; reconcile energy separately. Investigate residuals against measured uncertainty; no universal tolerance, invented yield or balancing emission. | jrc-ofc-2006; jrc-cww-2016; jrc-ilcd-2010 |
| validate_emissions | elementary outputs | Match species/CAS, medium/submedium and native unit, carbon origin and monitoring/LCIA definitions; NOx excludes N2O. Disjoint PM fractions, individual VOCs and named-P/residualP must not duplicate cumulative sums. Keep actual biogenic CO2. | jrc-cww-2016 |
| validate_disposition | products/wastes/releases | Require accepted co-product delivery, actual receiver/treatment and final discharge identification. No default sale, avoided-product credit or wastewater-as-release. Unknown UUIDs/background providers remain open; conditionally absent rows need evidence. | jrc-ofc-2006; jrc-cww-2016 |
| validate_completion | completed dataset | Retain row-level quantity sources, analytical uncertainty, coverage and unreviewed scope. Extend every additional actual exchange atomically. A complete PCR method does not certify a particular dataset, regulatory compliance or independent methodology review. |  |

## 10. Published Dataset Profile
