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 .beta.-bromoethyltribromobenzene in an alcohol as solvent.
