摘要： In the production of sodium aluminum hydride by reaction of an aluminum chloride etherate with sodium hydride in an inert liquid dispersing agent, the improvement which comprises using as said sodium hydride reagent coarse-grained sodium hydride which is first ground in said dispersing agent to a particle size less than about 12 microns; preferably the inert dispersible agent is tetrahydrofurane or a lower alkyl ether of a lower alkylene glycol, whereupon the resulting sodium aluminum hydride dissolves in the reaction medium.
