Production of crystalline tribromostyrene

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 β-bromoethyltribromobenzene in an alcohol as solvent.

Process for preparing ring halogenated styrenes

The present invention relates to the production of ring-halogenated styrene monomers of high purity. These are of value in the production of polymers which possess flame retardance. The process of the invention comprises reacting heterogenously ring halogenated beta-bromoethyl benzene with a strong aqueous alkali base in the presence of a quaternary phase transfer catalyst until substantially all the bromoethyl benzene has undergone reaction, separating the phases, washing and neutralizing the organic phase and recovering the ring-halogenated styrene monomer, which is the desired product.

Production of bromostyrenes

A process for the production of mono-, di-, and/or tribromostyrene which comprises reacting β-bromomethyl-mono-, di- and/or tribromobenzene at a temperature between 280°C to 470°C in the presence of a free radical source and either a lower alkanol or water.
