A process for preparing tribromoneopentyl chloroalkyl phosphates

摘要

A process of preparing tribromoneopentyl chloroalkyl phosphates comprising a first step of reacting phosphorus oxychloride with tribromoneopentyl alcohol and a second step of reacting the resultant formed in the first step with an alkylene oxide after a step of removing hydrochloric acid and unreacted phosphorus oxychloride present in the first reaction mixture to obtain a compound represented by the formula (1): <CHEM> , wherein R represents a hydrogen atom, or an alkyl or chloroalkyl group and n is from 0.95 to 1.15.
