Abstract: A process for dimerizing straight chain alpha-olefins having 3 to 8 carbon atoms using as a catalyst sodium metal dispersed upon the carbonate of an alkali metal having an atomic number of 19 to 55, inclusive, or of the metal barium. Dimerizations of propylene at about 1000 psi in the presence of a catalyst consisting of sodium dispersed on potassium carbonate give good yields of 4methylpentene-1.
