A method for preparing a metal borohydride salt, M(BH4)n, where n is 1 or 2, from a slurry of sodium borohydride and a sodium alkoxide in a liquid hydrocarbon is disclosed. The method includes combining the slurry with 0.99 to 1.01 equivalents of a metal salt, M(X)n, and methanol, wherein M is Li, K, Rb, Cs, Mg, Ca, Sr or Ba; and X is alkoxide; filtering to collect M(BH4)n; and separating oil and methanol liquid phases to obtain sodium methoxide in methanol solution.
