Manufacturing Process Flow

The production of diclorofosfato de fenilo involves a precisely controlled chemical synthesis pathway, ensuring high purity and consistent yield. The primary raw materials typically include Phenol and Phosphorus Oxychloride (POCl₃), reacted under specific conditions.

Detailed Process Steps:

1. Raw Material Preparation: High-grade Phenol and Phosphorus Oxychloride are precisely measured and pre-treated to ensure optimal reactivity and minimize impurities. Quality control checks are performed on incoming raw materials against internal standards and industry benchmarks such as ASTM E302.
2. Reaction (Phosphorylation): Phenol is slowly added to Phosphorus Oxychloride in a reaction vessel equipped with agitation and temperature control. The reaction is typically carried out under an inert atmosphere (e.g., nitrogen) to prevent oxidation and ensure selectivity. A catalyst may be employed to facilitate the reaction, which proceeds via electrophilic aromatic substitution, yielding Phenyl Dichlorophosphate along with hydrogen chloride (HCl) gas as a byproduct. Strict temperature management is critical to control reaction kinetics and minimize side reactions.
3. Byproduct Removal: The generated HCl gas is continuously removed from the reaction mixture, often by sparging with an inert gas or using a vacuum system, and then neutralized or scrubbed. Efficient removal of HCl drives the reaction to completion and prevents unwanted secondary reactions or equipment corrosion.
4. Purification (Distillation/Filtration): The crude product mixture undergoes a multi-stage purification process. This typically involves vacuum distillation to separate the desired diclorofosfato de fenilo from unreacted raw materials, catalysts, and any high-boiling byproducts. Advanced filtration techniques are often employed to remove particulate impurities, ensuring the final product meets stringent purity specifications.
5. Quality Control and Testing: Throughout the process, and especially after purification, rigorous quality control tests are performed. These include Gas Chromatography (GC) for purity and impurity profiling, Karl Fischer titration for moisture content, and acidity measurements. Products are tested against international standards like ISO 9001 and internal specifications, ensuring every batch of diclorofosfato de fenilo maintains consistent quality.
6. Embalaje: The finished product is packaged into appropriate container111s (e.g., drums, isotanks) under inert conditions, ensuring stability and preventing contamination during storage and transport. Packaging materials are selected for their chemical resistance and integrity, adhering to UN transportation regulations.

This meticulous process, often implemented in advanced chemical manufacturing facilities, ensures the production of high-grade diclorofosfato de fenilo suitable for demanding industrial applications. The typical service life of such chemical intermediates is largely tied to their shelf stability, which for Phenyl Dichlorophosphate is generally 12-24 months when stored under optimal, dry, and cool conditions in sealed container111s.
