Abstract

Methylpentenes, particularly 4-methylpentene-1, are obtained by dimerizing propylene in the presence of a hydride of potassium, rubidium or caesium at 120-225 DEG C. and 6-500 atmospheres. The catalyst is used in amounts of 0.5-20% by weight of the propylene used and may be supported on a carrier provided, this has no effect on the reaction, e.g. a carbonate, fluoride or oxide of potassium, rubidium, caesium or barium, or talc or powdered glass. A hydrocarbon diluent may be added. Batch or continuous processes may be employed using liquid or liquid-vapour phase reaction.
