  • Synthesis of complex beryllium hydrides
    Patent number: 4489051
    Abstract: Alkali metal beryllium tetrahydride is produced by heating a mixture of beryllium hydride and an alkali metal aluminum complex of the formulaMA1R.sub.m H.sub.nwherein M is an alkali metal, R is a hydrocarbyl group, m is an integer from 1 to 4, n is an integer from 0 to 3, the total of m and n being 4, the mixture having a BeH.sub.2 : MA1R.sub.m H.sub.n mole ratio above 1:1 (preferably at least about 1.5:1) to a temperature at which alkali metal beryllium tetrahydride of the formula M.sub.2 BeH.sub.4 is produced.
    Type: Grant
    Filed: January 23, 1984
    Date of Patent: December 18, 1984
    Assignee: Ethyl Corporation
    Inventor: Roy J. Laran
