ABSTRACT:
This invention relates to a process for the production of tetrabromobisphenol-A by the bromination of bisphenol-A, which process features: a water and water miscible solvent reaction medium; a relatively high reaction temperature; the presence, in the reaction medium, of unreacted Br.sub.2 during the feed of bisphenol-A to the reactor; and the oxidation of co-produced HBr to yield Br.sub.2.
