    摘要: Organic impurities in aqueous salt solutions; e.g., alkali or alkaline earth chloride solutions in particular, brines, are oxidized with chlorate ions at a pH of no greater than 5.0 and a temperature of at least 130.degree. C. to convert the organics to carbon dioxide. The process has particular applicability to oxidation of organic impurities in an aqueous brine solution derived from the saponification of a chlorohydrin to olefin oxide, prior to introduction of the brine into an electrolytic cell.
