    Abstract: Novel alkali metal beryllium hydrides of the formula M2BeH4, wherein M is alkali metal, are prepared by reaction of alkali metal aluminum alkyl hydrides with beryllium alkyls wherein the alkyl groups contain not more than about 10 carbon atoms. The new compounds are effective reducing components for high-energy fuels.

    Abstract: Hydrides of boron, particularly diborane, are prepared by reacting an organic ester of boric acid with aluminium metal and hydrogen at elevated temperatures. Suitable esters are listed, examples being triphenyl borate, trimethyl borate, tri-(t-butyl) borate, tricyclohexyl borate, tribenzyl borate and tri-(p-chlorophenyl) borate. Tertiary amines which form complexes with the boron hydrides may be present as diluents, examples of which are triethylamine, trimethylamine, and triphenylamine; diborane is obtained from these complexes by acidification with hydrochloric acid or boron trichloride at room temperature. Other diluents are specified, including alkyl, cycloalkyl and aromatic hydrocarbons and ethers. The aluminium is preferably in finely divided form and may have been activated by treatment with triethyl-aluminium and hydrogen at 140 DEG C. and 1000 lbs. per sq. inch pressure or by recycling excess aluminium from a previous run. Reaction temperature may be 120-300 DEG C., 140-180 DEG C. being preferred in the absence of a tertiary amine and 200-250 DEG C. when a tertiary amine is present. Hydrogen pressures of 500 to 5000 lbs. per sq. inch may be employed. The reaction may be catalyzed by trialkyl aluminium or boron compounds or by aluminium halides, especially aluminium chloride. The boron hydride or its complex with the tertiary amine is removed from the product by distillation; by-product aluminium alcoholate may be recovered and hydrolysed to form the alcohol which is reacted with boric oxide to produce boron alcoholate for re-use in the process.
