Abstract
A process for the preparation of lithium aluminum hydride in an ethereal solvent via the metathesis of sodium aluminum hydride and lithium chloride in a one direct step reaction comprising heating together sodium aluminum hydride and lithium chloride in an ethereal solvent at a temperature of 25.degree. C. to the reflux temperature of the solvent until the reaction is complete.
Claims5
A process for the preparation of lithium aluminum hydride in an ethereal solvent via the metathesis of sodium aluminum hydride and lithium chloride in a one direct step reaction without a prior sodium aluminum hydride solution forming step and without a cosolvent or a catalyst comprising adding sodium aluminum hydride without a sodium aluminum hydride solution forming step to lithium chloride and an ethereal solvent and heating together said sodium aluminum hydride and lithium chloride in said ethereal solvent at a temperature of 25.degree. C. to the reflux temperature of the solvent, under an inert atmosphere, until the reaction is complete.
