ИСТИНА

A process for preparing bromobutyl comprising exposing bromine-containing agent for the butyl rubber solution to form a reaction mixture containing the desired product were formed by neutralizing and washing the reaction mixture and its separation into the desired product and bromine-containing waste liquid, from which the recovery of bromine is carried out, which is carried out by forcing the mass transfer direct liquid waste generated during the production of neutralizing and target product washing, with an oxidizing agent and the hydrocarbon extractant which together fed into the mass transfer zone is carried out simultaneously oxidation contained in liquid waste bromine compounds and the extraction of bromine, followed by isolation of the products of the mass transfer of the formed bromine extract which is used as a holding Broms agent during the formation of the reaction mixture containing the desired product.
