Abstract

Hexenes are obtained by dimerizing propylene in the presence of an alkali metal hydrocarbon at 40 DEG -225 DEG C. and atmospheric to 150 atmospheres pressue. The hydrocarbon radical in the catalyst may be ethyl, propyl, butyl, amyl, hexyl, propenyl, butenyl, hexenyl, phenyl, naphthyl or benzyl or more especially allyl. Sodium compounds yield 4- and 2-methyl-pentene-2 and potassium compounds 4-methyl-pentene-1. A hydrocarbon solvent may be used. Reaction is effected in the vapour, liquid or mixed phases in batch or continuous operation using a fixed, fluidized or suspended catalyst which may be on a carrier. The catalyst is added in amounts of 0,01-10% by weight of propylene or at a propylene to catalyst mol. ratio of 2-500:1.
