FIELD: chemistry.
SUBSTANCE: present invention pertains to the method of producing dichloroanhydride of styryl phosphonic acid and can be used in chemical industry in the production of organic phosphorus compound preproducts. The method involves reacting styrene with phosphorous pentachloride in an inert solvent and disintegration of the obtained styrene adduct using a carbonyl compound. The method is distinguished by that, the carbonyl compound used is urea or its derivatives, and disintegration of the adduct takes place at room temperature.
EFFECT: design of a new efficient method of producing dichloroanhydride of styryl phophonic acid.
