Abstract
Olefin oxide is produced by reacting chlorine, obtained from an electrolysis cell, with a tertiary alkanol and an aqueous solution, containing sodium hydroxide and sodium chloride, obtained from the cathode of an electrolysis cell, to produce a tertiary alkyl hypochlorite. The hypochlorite is then reacted in a chlorohydrin reactor with an olefinically unsaturated compound and water, essentially free of chloride ions, to produce the corresponding chlorohydrin. The chlorohydrin is recovered and saponified with cell liquor, containing sodium hydroxide and sodium chloride, obtained from the cathode compartment of the cell to produce the olefin oxide.
