Abstract

A process for preparing 4-methyl-1-pentene comprising dimerizing propylene in the presence of an alkali metal catalyst at 120~200"J and 1000 psi~2000Psi.The alkali metal catalyst suitable for use in the present process includes potassium, sodium or a potassium/sodium alloy supported on a porous potassium carbonate carrier. The carrier contains various amounts of carbon-containing compounds in the form of powder as a promoter which enhances the 4-methyl-1-pentene selectivity of the dimerization reaction and the strength of the carrier.
