ALKALI METAL ALUMINUM HYDRIDE PRODUCTION Abstract of the Disclosure . A process for the production of alkali metal aluminum tetrahydrides from its elements by pressure hydrogenation, particularly characterized by production from an aluminum containing a reaction-promoting quantity of titanium, zirconium, hafnium, vanadium, niobium, or uranium. Titanium is preffered in a quan- tity of about 300 parts per part by wieght aluminum. The process is preferably carried out on a semi- continuous basis in the presence of an alkali metal aluminate which is carried through to successive batches as an active heel. Another aspect disclosed is a process for the production of alkali metal aluminum tetrahydrides from aluminum and alkali metal in which the reactants are preferably in stoichiometric pro- portions, leaving no heel after pressure hydrogenation in an ether reaction medium in the presence of an aluminum-containing catalyst.
