    摘要: Trimethylaluminum is made by an alkyl exchange process by first reacting a trialkylaluminum which has at least two carbon atoms in its alkyl groups with a methyl halide, optionally in the presence of an alkyl exchange catalyst, and then fractionally distilling trimethylaluminum from the product mixture in the presence of trialkylaluminum having at least two carbon atoms in its alkyl groups so as to convert the dimethylaluminum halide by-product of the alkyl exchange reaction into trimethylaluminum.

    摘要: Hydrocarbon solvent solutions of alkylaluminoxane are made by mixing trimethylaluminum and a hydrocarbylaluminum compound, which compound contains at least one hydrocarbyl group having 2 or more carbon atoms, in a hydrocarbon solvent and thereafter adding water or a hydrated compound so as to form a solution of alkylaluminoxane in said solvent.
