Tris(2-Chloroethyl) Phosphate Bulk Procurement Specs & Data
Procurement of industrial-grade organophosphates requires rigorous validation of physical constants and chemical purity to ensure downstream polymer stability. When sourcing Tris(2-Chloroethyl) Phosphate (CAS: 115-96-8), technical buyers must prioritize data regarding hydrolysis stability, acid value, and specific gravity over generic marketing claims. This chlorinated phosphate ester serves dual functions as a flame retardant and a plasticizer additive, necessitating strict adherence to specification sheets to prevent catalyst poisoning or phase separation in final formulations. The following technical breakdown outlines the critical parameters required for qualifying bulk supply chains.
Essential Technical Indicators for Tris(2-Chloroethyl) Phosphate Bulk Procurement Specs
The primary determinant of quality for Phosphoric acid tris(2-chloroethyl) ester lies in its physical consistency and impurity profile. Deviations in specific gravity or water content can significantly alter the stoichiometry in polyurethane and PVC systems. Procurement specifications must mandate a colorless to light yellow oily transparent liquid appearance, indicating minimal oxidation or thermal degradation during synthesis. The specific gravity at 15/20°C should remain within the tight range of 1.410 to 1.430. Values outside this window often suggest contamination with lighter solvents or incomplete chlorination.
Acid value is a critical metric for predicting corrosion potential and catalyst interference. A specification limit of ≤ 1.0 mgKOH/g is standard for high-grade material. Elevated acid values indicate residual hydrochloric acid or phosphate mono/diesters, which can degrade polymer matrices over time. Furthermore, water content must be controlled at ≤ 0.3% to maintain hydrolysis stability, particularly when the material is stored in humid conditions or used in moisture-sensitive reactions. The flash point, typically ≥ 210°C, classifies the material for transport and storage safety protocols.
At NINGBO INNO PHARMCHEM CO.,LTD., quality control focuses on these precise physical constants to ensure drop-in replacement capability for existing formulations. Buyers should verify these parameters against a recent Certificate of Analysis (COA) before finalizing supply agreements.

| Parameter | Standard Specification | Test Method | Impact on Application |
|---|---|---|---|
| Appearance | Colorless to Light Yellow Transparent Liquid | Visual / APHA | Indicates purity and lack of thermal degradation |
| Specific Gravity (15/20°C) | 1.410 - 1.430 | ASTM D4052 | Ensures correct dosing by weight in formulations |
| Acid Value (mgKOH/g) | ≤ 1.0 | Titration | Prevents catalyst poisoning and polymer corrosion |
| Water Content (%) | ≤ 0.3 | Karl Fischer | Maintains hydrolysis stability and prevents foaming |
| Flash Point (°C) | ≥ 210 | Pensky-Martens | Determines storage classification and safety handling |
Quality Assurance Protocols and Batch Consistency for TCEP Flame Retardant Supply
Consistency across production batches is paramount for industrial manufacturers integrating TCEP into continuous processing lines. Variability in viscosity or purity can lead to downstream defects such as surface blooming, reduced tensile strength, or inconsistent flame retardancy. Quality assurance protocols must include gas chromatography-mass spectrometry (GC-MS) analysis to confirm the absence of unintended byproducts or isomers. High-performance liquid chromatography (HPLC) is also employed to quantify the main component purity, ensuring it meets the threshold for effective flame suppression.
Batch consistency is verified through retention samples and longitudinal stability testing. A reliable supplier will maintain records of key parameters over multiple production runs to demonstrate process control. This data is crucial for procurement managers validating a new vendor against incumbent supplies. The material is miscible with ordinary organic solvents but insoluble in aliphatic hydrocarbons; therefore, solvent compatibility tests should be part of the incoming quality control (IQC) process. Ensuring the Chlorinated phosphate ester maintains its light cream taste profile without pungent odors indicates proper handling during synthesis and distillation.
Regulatory Compliance and Safety Data Sheet Standards for Tris(2-Chloroethyl) Phosphate
Safety documentation for Tris(chloroethyl)phosphate must align with Globally Harmonized System (GHS) standards for classification and labeling. The Safety Data Sheet (SDS) provides critical handling instructions to mitigate occupational exposure risks. Users must avoid breathing vapor and mist during transfer operations. Engineering controls such as local exhaust ventilation are recommended when handling bulk quantities to maintain airborne concentrations below exposure limits. In case of direct contact with eyes or skin, immediate rinsing with plenty of water is required, followed by medical advice if irritation persists.
Ingestion protocols dictate rinsing the mouth immediately with water and seeking professional medical attention. Protective clothing, including chemical-resistant gloves and eye protection, is mandatory during drum handling or sampling. The SDS should also outline fire-fighting measures, noting that while the product contributes to flame retardancy in polymers, bulk fires require specific extinguishing media suitable for chemical fires. Manufacturers must be committed to ensuring the health and safety of customers and employees by providing up-to-date SDS documentation with every shipment. Regulatory compliance focuses on accurate hazard communication rather than unverified certification claims.
Packaging Logistics and Storage Specifications for Bulk TCEP Orders
Proper packaging preserves the chemical integrity of Tris(2-Chloroethyl) Phosphate during transit and storage. The material is typically supplied in steel drums or Intermediate Bulk Containers (IBCs) lined with compatible materials to prevent contamination. Storage facilities should be cool, dry, and well-ventilated to prevent moisture uptake, which could exceed the 0.3% water content specification. Since the product has good hydrolysis stability, it can be stored for extended periods provided the containers remain sealed and intact.
Logistics planning must account for the specific gravity of 1.410-1.430 when calculating load weights for transport. Palletization should ensure stability to prevent drum rupture. The product is widely used in cellulose acetate, nitrocellulose varnish, and polyvinyl chloride applications, meaning supply chains often serve diverse manufacturing sectors. Inventory rotation should follow a first-in-first-out (FIFO) protocol to ensure the freshest material is utilized in sensitive polymer formulations. Temperature fluctuations should be minimized to prevent condensation inside storage vessels, which could introduce water into the bulk liquid.
Validating Performance Metrics for Tris(2-Chloroethyl) Phosphate in Polymer Applications
The efficacy of Tris(2-Chloroethyl) Phosphate as a flame retardant is validated through its performance in final polymer matrices. In addition to self-extinguishing properties, the product acts as a plasticizer, improving the physical properties of the finished good. The product feels soft and can enhance flexibility in rigid applications. It is the main flame retardant material for manufacturing flame retardant cable three-proof tarpaulin and flame retardant rubber conveyor belts. The general addition amount ranges from 10-15%, depending on the required fire resistance rating and mechanical property targets.
Performance benchmarking involves testing limiting oxygen index (LOI) and vertical burn rates in compounded samples. The material is also used as a petroleum additive and an extractant of olefinic elements, showcasing its versatility beyond polymer additives. For formulators working with polyurethane systems, understanding the interaction between the phosphate ester and polyol components is essential.
