ABSTRACT:
Caustic requirements are substantially reduced in the treatment of epoxidate from olefin/ethylbenzene hydroperoxide epoxidation by treating the epoxidate products with an aqueous stream comprised of alkali metal carbonate, separating a phenol-containing 1-phenyl ethanol fraction from the treated expodiate, separating phenol from the 1-phenyl ethanol fraction by treatment with basic anion exchange resin, regenerating the resin with aqueous alkali metal hydroxide, and converting alkali metal hydroxide from the resin regeneration to alkali metal carbonate for use in the epoxidate treatment.
