ABSTRACT:
In an integrated process for electrolytic production of chlorine and the production of an olefin oxide via the chlorohydrin wherein the chlorohydrin is contacted with an aqueous solution of sodium hydroxide and sodium chloride from the cathode compartment of an electrolytic cell, to produce the oxide and brine, the brine is contacted with gaseous chlorine to oxidize organic impurities to volatile organic fragments, which are stripped from the brine, prior to recycling the brine to the electrolytic cell.
