Abstract
The effluent from the reaction of HCl with a molecular-oxygen-containing gas, e.g. air, in the presence of a variable oxidation state catalyst, is mixed with an aqueous salt solution containing at least 50 ppm of bromine to liberate elemental bromine. Suitable salt solutions include sea water, natural brines (e.g. Dead Sea and Israel brine) and artificial brines (e.g. by-products from the salt industry). 50-70 volume per cent of air and 30-50 volume per cent of moist or anhydrous HCl can be reacted in the presence of a copper chloride mixture mounted upon an inert carrier, e.g. silica, silica gel, alumina, pumice, asbestos, kieselguhr or diatomaceous earth. The HCl oxidation may be conducted at 300 DEG -700 DEG C. and at a pressure from atmospheric ot 100 p.s.i. The bromine liberated may be extracted into the gas phase in a blowing-out tower by air, this gas phase then being contacted with SO2 and H2O (or NO) to form a HBr solution in H2SO4, the HBr is oxidized with Cl2 (preferably another portion of the effluent) and heated to liberate and separate elemental bromine from the solution.
