Abstract
Glycidol is prepared by epoxidizing propylene to propylene oxide by reaction with an organic hydroperoxide in the liquid phase and in the presence of a metal epoxidation catalyst, isomerizing the propylene oxide to allyl alcohol and epoxidizing allyl alcohol to glycidol by reaction with an organic hydroperoxide in the liquid phase in the presence of a metal epoxidation catalyst. The glycidol may be hydrolysed to glycerine, e.g. with water at 20-200 DEG C. in the presence of an acidic or basic catalyst. Specified epoxidation catalysts are compounds of Ti, V, Cr, Se, Zr, Nb, Te, Mo, Ta, W, Re and U. Vanadium catalysts are preferred, especially for the epoxidation of allyl alcohol. The preferred hydroperoxide is a -phenylethyl hydroperoxide. The two epoxidation reactions may be effected simultaneously. The combined effluents from the epoxidation stages may be treated for the recovery of the alcohol corresponding to the hydroperoxide; acetophenone may also be recovered when a -phenylethyl hydroperoxide is used.
