ABSTRACT:
An effective two stage process for the production of sodium aluminum tetrahydride which facilitates use of equipment at moderate hydrogen pressure of 700-1500 psig. An aluminum alkyl is added to provide a catalyst species in a hydrocarbon reaction medium containing aluminum and sodium reactants. A reaction at about 130.degree.-170.degree. C. is carried out to form Na.sub.3 AlH.sub.6. The reaction temperature is then lowered to about 80.degree.-120.degree. C. and the hydrogen pressure is continued to convert the Na.sub.3 AlH.sub.6 to NaAlH.sub.4.
