Abstract

1,127,987. Epoxidation of olefins. HALCON INTERNATIONAL Inc. 20 July, 1966 [21 July, 1965], No. 32610/66. Heading C2C. Olefinically unsaturated compounds are epoxidized by reacting with ethylbenzene hydroperoxide or cumene hydroperoxide in the presence of an epoxidation catalyst and recovering and reusing the catalyst, alpha-phenyl ethanol or alpha-alpha-dimethyl benzyl alcohol being removed from the recovered catalyst stream to the extent that the amount in the total feed to subsequent epoxidation does not exceed 5 or 20% by weight respectively. Preferred catalysts are the naphthenates and carbonyls of molybdenum, vanadium, tungsten, titanium, rhenium, tantalum, niobium and selenium. The olefinically unsaturated compound may be a hydrocarbon, e.g. an olefin, a cycloolefin, styrene, methyl styrene, vinyl cyclohexane, a phenyl cyclohexene or may carry substituents, e.g. allyl alcohol, methallyl alcohol, cyclohexenol, diallyl ether, methyl methacrylate, methyl oleate, methyl vinyl ketone and allyl chloride. The oxidation is preferably carried out in the presence of an organic solvent in the presence of a basic compound, e.g. basic salts of the alkali metals.
