1. A process for preparing crystalline, substantially nonsolvated aluminum hydride which comprises, A. DISSOLVING ALUMINUM CHLORIDE IN DIETHYL ETHER AND RECOVERING ALUMINUM CHLORIDE.MONODIETHYL ETHERATE FROM THE RESULTING ETHEREAL SOLUTION, B. REACTING SAID ALUMINUM CHLORIDE-MONODIETHYL ETHERATE WITH A LIGHT METAL HYDRIDE THEREBY PREPARING AN ALUMINUM HYDRIDE.ALUMINUM CHLORIDE.DIETHYL ETHER COMPLEX, C. REACTING SAID ALUMINUM HYDRIDE.ALUMINUM CHLORIDE.DIETHYL ETHER COMPLEX IN THE LIQUID STATE WITH LITHIUM ALUMINUM HYDRIDE THEREBY TO PREPARE AN ETHEREAL PRODUCT SOLUTION CONTAINING ALUMINUM HYDRIDE-DIETHYL ETHER SOLVATE, D. SEPARATING SAID PRODUCT SOLUTION FROM CO-PRODUCED SOLID BYPRODUCTS, AND E. RECOVERING A SOLID, CRYSTALLINE, SUBSTANTIALLY NON-SOLVATED ALUMINUM HYDRIDE FROM SAID ETHEREAL PRODUCT SOLUTION. |
