Abstract
Amine alane decomposition is catalyzed by titanium. This effect of titanium can be suppressed by treating it with a passivating agent such as air, nitrous oxide, carbon monoxide and alkyl nitrites. Such agents may be used (1) to treat titanium-containing NaAlH.sub.4 preparations to be used in preparing amine alanes, or (2) to treat amine alanes containing titanium as an impurity, e.g. in finely divided form. Furthermore, the reaction of NaAlH.sub.4, amine, and a halide substance to produce an amine alane can be conducted in the presence of a passivating agent.
