Abstract
A process for the simultaneous production of bromostyrene or dibromostyrene and of an alkyl bromide, which comprises reacting bromoethyl bromobenzene or bromoethyl dibromobenzene with an alkanol at an elevated temperature. When only these reactants are reacted, the temperature is between 400.degree.C and 550.degree.C; when the reaction is effected in the presence of a source of free radicals, the temperature used can be lower, and temperatures of about 300.degree.C are adequate.
