METHOD FOR THE PRODUCTION OF alpha-ALANE |
摘要 |
<p>A method of forming alpha-alane. The method includes reacting aluminum trichloride and an alkali metal hydride to form an alane-ether complex solution. An aqueous ether solution is optionally added to the alane-ether complex solution to form a partially hydrolyzed ether/alane-ether complex solution. A solution of a crystallization additive is added to the alane-ether complex solution or to the aqueous ether/alane-ether complex solution to form a crystallization solution. The crystallization additive is selected from the group consisting of squalene, cyclododecatriene, norbornylene, norbornadiene, a phenyl terminated polybutadiene, 2,4-dimethyl anisole, 3,5-dimethyl anisole, 2,6-dimethyl anisole, polydimethyl siloxane, and mixtures thereof. Ether is removed from the crystallization solution to crystallize the alpha-alane.</p> |
