ABSTRACT:
This invention relates to a process for the production of tetrabromobisphenol-A by the bromination of bisphenol-A, which process features the addition of bisphenol-A to a reaction mass containing unreacted Br.sub.2 and 30 to 85 wt % water and an alcohol solvent, the reaction mass being at a relatively high temperature.
