| titleOfInvention | Process for making phosphonic acid ester chlorides |
| abstract | The disclosure relates to a process for making phosphonic acid ester chlorides of the general formula (I) n n R--P(O) ClOR' (I) n n in which R stands for an alkyl group with 1 to 6 carbon atoms or an aryl group and R' stands for an alkyl group with 1 to 20 carbon atoms or an aryl group. More particularly, a compound of general formula (II) n n R--PCl.sub.2 (II) n n is reacted with a sulfuric acid monoester of general formula (III) n n R'--O--SO.sub.3 H (III) n n R and R' in formulae (II) and (III) having the meanings given above; the reactants are used in about equimolar proportions and the reaction is effected at a temperature of from -20° C. to 50° C. After termination of the reaction, the phosphonic acid ester chloride is separated from the reaction mixture by subjecting this latter to distillation under vacuum. |
