Abstract
An economically attractive Redistribution Process for the production of trimethylaluminum and numerous alkylaluminum bromides and iodides is described herein. The Redistribution Process is a chemical reequilibration reaction which consists of forming a mixture of a methylaluminum bromide or iodide with aluminum trialkyl followed by separating by distillation, trimethylaluminum from the alkylaluminum bromides or iodides. The preferred method for separating the mixture of methylaluminum bromide or iodide and aluminum trialkyl into trimethylaluminum and alkylaluminum bromide or iodide is fractional distillation. Trimethylaluminum and the alkylaluminum bromides and iodides are valuable commercial materials for use as co-catalysts for the polymerization of various unsaturated hydrocarbons. Trimethylaluminum is also employed as a methylating agent, a chemical intermediate and a pyrophoric fuel.
