A process for producing an epoxy compound by chlorinating a tertiary alkanol to the corresponding hypochlorite, followed by reaction of the hypochlorite with water and an olefinically unsaturated compound to produce the corresponding chlorohydrin and saponification of the chlorohydrin to the corresponding epoxy compound. The hypochlorite production and the saponification are effected with calcium oxide in an aqueous solution of calcium chloride, with calcium chloride being produced as by-product in an aqueous solution having a calcium chloride concentration of at least 25 wt. %. In this manner, calcium chloride by-product is recovered in a more usable form thereby eliminating the problems associated with recovery of calcium chloride by-product.
