    Abstract: 1. A method for the preparation of magnesium aluminum hydride which comprises reacting sodium aluminum hydride with an anhydrous magnesium halide in an ether as reaction solvent said ether being selected from the group consisting of unsubstituted alkyl ethers, diethylene glycol dialkyl ethers, and tetrahydrofuran mechanically separating the impure solid reaction products, separating magnesium aluminum hydride etherate from said reaction product by treatment with an ether as extractant for said etherate said ether being selected from the group consisting of unsubstituted alkyl ethers, diethylene glycol dialkyl ethers and tetrahydrofuran removing said extractant from the extract by evaporation thereof to dryness, removing the complexed ether by heating said etherate under reduced pressure to a temperature not in excess of 100* C. and recovering essentially ether-free magnesium aluminum hydride.
