    Abstract: In a process for orthoalkylating an aromatic amine such as aniline by reaction of the aromatic amine with an olefin and a catalytic amount of an alkyl aluminum halide, the improvement whereby the catalyst is removed after the alkylation by adding to the reaction mixture aqueous caustic in an amount sufficient to provide from about 1.2-6 equivalents of caustic per equivalent of halogen, aging the caustic treated mixture at about 75*-175* C. for a period of from 15 minutes to 3 hours, separating the aqueous phase and adding to the aqueous phase at a temperature of about 20*-50* C. an amount of a weakly acidic material sufficient to reduce the pH to less than about 9.5, and then filtering off the precipitated alumina. This improved aluminum extraction process allows removal of the aluminum content of the alkylation in a readily recoverable, useful form.

    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.
