    • The process involves (a) continuously forming bromine chloride from separate feed streams of bromine and chlorine by maintaining said streams under automatic feed rate control whereby the streams are continuously proportioned to come together in equimolar amounts to form bromine chloride; (b) continuously forming an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), a pH of at least 7, and an atom ratio of nitrogen to active bromine greater than 0.93:1 by continuously feeding into mixing apparatus separate feed streams of (1) bromine chloride formed in (a), and (2) an aqueous solution of alkali metal salt of sulfamic acid, under automatic feed rate control whereby the feed streams are continuously proportioned to come together in amounts that produce an aqueous product having an active bromine content of at least 100,000 ppm (wt/wt), a pH of at least 7, and an atom ratio of nitrogen to active bromine from (1) and (2) greater than 0.93:1; and, (c) withdrawing said aqueous product from said mixing apparatus at a rate sufficient to enable the continuous feeding in (a) and (b) to be maintained.

    • Described is a process for separating an organic phase comprising mainly propyl bromide from a crude reaction mixture formed by free-radical catalyzed hydrobromination of propylene with hydrogen bromide. The process comprises (A) feeding cold water into an upper or mid-portion of a packed column; (B) concurrently feeding the crude reaction mixture into an upper portion and/or mid-portion of the column so that the water contacts the crude reaction mixture; to form a mixture of (i) an acidic aqueous phase comprising aqueous hydrogen bromide and (ii) an organic phase comprising propyl bromide; (C) withdrawing the resultant phases from said column, at a rate comparable to the feeds being made into the column; and (D) separating the phases to form an upper acidic aqueous phase comprising aqueous hydrogen bromide superposed on a lower liquid organic phase comprising propyl bromide, and separating these upper and lower phases from each other.
