Abstract

4-Methylpentene-1 is obtained by dimerizing propylene in the presence of a compound of graphite with potassium, rubidium or caesium or such a compound which has been treated with hydrogen. Potassium is the preferred alkali metal used in amounts of 5-29% by weight of the compound (29% is equivalent to C8K). Reaction is effected at 100-250 DEG C., 1-200 atmospheres and an L.H.S.V. of 0-5-5. An inert diluent, e.g. hexane, pentane or propane may be present in amounts up to 100 volumes per volume of propylene. The catalyst is prepared by heating the components together, e.g. under nitrogen at 250 DEG C.; treatment with hydrogen may be effected at 250-275 DEG C. and is thought to convert the metal to its hydride.
