| titleOfInvention | Process for the simultaneous manufacture of dimethylaluminum chloride and alkylaluminum chlorides |
| abstract | A redistribution process for the simultaneous production of dimethylaluminum chloride and numerous alkylaluminum chlorides is described herein. The redistribution process is a chemical reaction which consists of first forming a mixture of methylaluminum dichloride and at least one alkylaluminum compound selected from the group consisting of an aluminum trialkyl, a dialkylaluminum chloride, and an alkylaluminum sesquichloride, where "alkyl" refers to a group containing 2 to 16 carbon atoms. The relative amounts of the mixture components are fixed such that the mixture has a chlorine-to-aluminum atomic ratio of 1.0 to 2.0. The mixture thus formed is next subjected to a fractional distillation, in which a first fraction is obtained, consisting of dimethylaluminum chloride, essentially free of trimethylaluminum, methylaluminum dichloride, and other impurities. The distillation residue consists essentially of alkylaluminum chlorides, which are valuable commercial materials. Dimethylaluminum chloride itself is useful as a methylating agent, a polymerization cocatalyst, a chemical intermediate, and a pyrophoric fuel. |
