Abstract
In the direct synthesis process for producing NaAlH.sub.4 (pressure hydrogenation of Na and Al in a liquid phase reaction medium at an elevated temperature) advantages are realized by insuring that the initial reaction mixture contains a small amount of water and/or an alcohol. In particular, the induction period is shortened. And, the time, trouble and expense of purifying and pre-drying the reaction medium are avoided.
