Abstract

1489832 Olefinic alcohols COMPAGNIE FRANCAISE DE RAFFINAGE 14 Feb 1975 [22 Feb 1974] 6455/75 Heading C2C [Also in Divisions B1 and C5] Beta-olefinic alcohols are produced in admixture with diolefins by the dehydration of diols in contact with a catalyst comprising calcium pyrophosphate either alone or in admixture with at least one pyrophosphate, whether mixed or not, of Li, Na, Sr and Ba, and/or at least one neutral orthophosphate, whether mixed or not, of Li, Na, Sr, Ba and Ca. The dehydration may be effected in the liquid phase or in the vapour phase at 250-600‹ C. and a volume space velocity of 0À1-5 hr.<SP>-1</SP>. The diol may be pure, diluted with inert gas or mixed with olefinic alcohols. The examples describe the dehydration of methyl-2,3-butanediol to give 2-methyl-1-butene-2-ol and isoprene. Carbonyl compounds and 2-methylepoxy-2,3- butane may be produced as by-products.
