ABSTRACT:
A preferred process for producing a brominated, non-fused aromatic composition involves a continuous bromination in a continuous, mixed reactor such as a continuous stirred tank reactor. Bromine and the aromatic substrate, and optionally a bromination catalyst, are continuously fed to a reaction zone to form a reaction mixture, and the reaction mixture is continuously withdrawn from the reaction zone after an established average residence time. Bromination levels can be readily controlled by controlling the average residence time of the reaction mixture within the reaction zone. Preferred continues processes also provide mixed, brominated compositions having product distributions which are substantially broader than that obtained by batch brominations conducted to achieve the same level of bromination. Preferred products thus have broad melting ranges which are advantageous in compounding operations.
