Abstract

1,149,281. Purification of primary monohydric alcohols. DEUTSCHE ERDÍL A.G. 2 June, 1967 [24 Sept., 1966], No. 25530/67. Heading C2C. Primary monohydric alcohols containing more than 4 C atoms in the molecule and being in admixture with an impurity which comprises a diol containing a secondary hydroxyl group are purified by subjecting the diol to catalytic dehydration in the liquid phase preferably in the presence of a catalyst comprising an oxide of Al, Zr or Ti at a temperature of between 130‹ C. and 280‹ C. The unsaturated compounds so formed are then hydrogenated by any known process, preferably using a nickel catalyst at a temperature of between 110‹ C. and 130‹ C. and at a hydrogen pressure of 10-30 atmospheres. The examples describe the purification of C 12-14 , C 16-18 and C 8-18 alcohol cuts.
