Abstract
The invention to preparing alane-etherate and alane by producing an alane-etherate complex using an acid including one or a combination of hydrochloric acid and methanesulfonic acid and a metal tetrahydroaluminate in a solvent including an ether such as diethyl ether. The alane-etherate can be desolvated using a spray desolvation process such as electrospraying.
