Abstract

2-methylpentene-2 is obtained by dimerising propylene in the presence of a lamellar complex of potassium and carbon, having the formula KCx in which x is 24 or more, the carbon having an ash content of 0.6% by weight or more when x is 24. x may be 24, 36, 48 or 60 and the carbon is preferably graphite and may contain trace impurities, e.g. iron, silicon or aluminium, present in the carbon as obtained or added to the carbon or complex. The complex may be formed in situ and a free alkali metal, preferably potassium, supported on carbon or free carbon may be present. Reaction is effected at 150-200 DEG C. and 50-4,000 p.s.i.g. in the presence of a hydrocarbon solvent. Water, oxygen, allene or methylacetylene should be absent from the feed but inert gases, p e.g. nitrogen, methane, ethane or propane may be present. The catalyst may be fixed, fluidised or used as a slurry. Specifications 824,917, 825,902 and 912,826 also are referred to.
