Some Revised Industrial Preparations for Alkylauminum Compounds

Two improved preparation methods for alkylaluminum compounds have been developed. Triisobutyl aluminum is produced in higher yield, at a higher reaction rate and under lower reaction pressure than by previous methods by employing aluminum powder containing trace amounts of titanium as the raw material and performing the reaction under low hydrogen partial pressure. Trimethyl aluminum is produced in higher yield than by the common sesqui process by employing pulverized melt-sprayed aluminum-magnesium alloy as the raw material. The product is obtained by mixing the raw material with excess amounts of methyl chloride in a glass bead mill
