Process for preparing ring halogenated styrenes |
| abstract |
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. |
