Abstract
Substantially colourless epoxy alcohols are recovered from a crude oxidate by distilling said oxidate in a first column to recover unreacted olefin present as an overhead fraction, distilling the base product from the first column in a second column to recover a second overhead fraction comprising only monooxygenated compounds and epoxyalcohols and subsequently fractionating said second overhead fraction in at least one further column to recover the epoxy alcohols. The crude oxidate is defined as that obtained by (1) liquid phase oxidation of monoolefins with molecular oxygen in the presence of a catalyst selected from the metals of Groups IVA, VA and VIA or their compounds, excluding Cr, or by (2) liquidphase autoxidation of monoolefins in a first stage, followed by re-arrangement of the hydroperoxides so formed in a second stage by treatment with a catlyst of the type used in method (1). Both these methods give rise to coloured impurities comprising heavy, or high-boiling material and these impurities remain as a base product in the second column in the present process. An example relates to the recovery of 3,4 - epoxy - 4 - methylpentanol - 2 and 3,4-epoxy-2 -methylpentanol-2.
