Abstract

A process for the production of an olefinic hydrocarbon having a carbon chain of at least 4 atoms from an isomeric olefinic hydrocarbon having the same carbon atom configuration comprises contacting the latter hydrocarbon with an alkali metal or alkali metal hydride disposed on the surface of a support, such as activated carbon having a surface area of 500-1200 m2/g., at a temperature of 120-225 DEG C., to effect the isomerization. The initial hydrocarbon may be a methyl-pentene, for example a mixture obtained by the dimerization of propylene. The process may be effected in the vapour or the liquid phase, for example in a suitable solvent.
