PRODUCTION OF CRYSTALLINE TRIBROMOSTYRENE

摘要

The invention relates to an improved process for the production of crystalline tribromostyrene. The process involves removal of hydrogen bromide in a two phase system with the aid of phase transfer catalysts. One of the phases used is an aqueous one containing an alkali metal hydroxide whereas the second comprises bromoethyltribromobenzene in an alcohol as solvent. The product prepared by the process of the present invention is a known monomer imparting fireretarding properties to polymers containing it.
