Abstract

A process for the prevention and/or elimination of foam in the production of bromine comprises the step of mixing with the feed brine an amount of up to 20 ppm of an anti-foam silicon-free compound containing hydroxyl groups, wherein said ppm amount refers to the weight of the anti-foam in the total feed brine.
