Abstract

Epoxy alcohols are recovered from the crude oxidate obtained by oxidizing mono-olefins by treating the oxidate with alkali to remove any acids and subsequently distilling the treated oxidate to isolate the epoxy alcohols. The oxidate is defined as that obtained by (1) liquid phase oxidation of monoolefins with molecular oxygen in the presence of catalysts selected from metals of Groups IVA, VA or VIA, or their compounds, but excluding Cr, or by (2) liquid phase autoxidation of mono-olefins in a first stage, followed by re-arrangement of the hydroperoxides so formed in a second stage by treatment with the catalysts used in method (1). The acid-removal treatment may be effected between the autoxidation and re-arrangement stages in method (2). Both methods give rise to small amounts of carboxylic acid and percarboxylic acids in the oxidate. The alkali may be solid or in aqueous solution, e.g. NaOH, Na2CO3 or Ca(OH)2 and is generally used in amounts of 0.5-10 times the stoichiometric amount required to neutralize the acids. An example relates to the recovery of 3,4-epoxy-4-methylpentanol-2 and 3,4-epoxy-2-methyl-pentanol-2.
