dimethyl chlorophosphate - Production method
The production of dimethyl phosphite chlorination is generally used in China, that is, dimethyl phosphite is prepared by the reaction of phosphorus trichloride and methanol, and then chlorinated with chlorine.
Under the condition of vacuum degree> 86.7 kPa, phosphorus trichloride and methanol are mixed and reacted in a certain proportion, and the by-products chloromethane and hydrogen chloride gas are separated, deacidification is removed, and the film is deacidification again at a higher temperature. Cooling to obtain dimethyl phosphite. After content analysis, chlorine gas is introduced in a certain proportion under high vacuum conditions to obtain the product. The total yield of esterification and chlorination is above 90%.
This product is a colorless transparent liquid, decomposed in water, soluble in alcohol, benzene, carbon tetrachloride and other organic solvents.
