ABSTRACT:
High purity tetrahydrocarbylammonium tetrahydridoborates are prepared under anhydrous conditions by reacting tetrahydrocarbylammonium salts with at least 8% molar excess of an alkali metal hydroxide in the presence of ethanol to produce the corresponding tetrahydrocarbylammonium hydroxides and alkali metal salts, removing the alkali metal salts and adding an alkali metal borohydride to the solution to produce the corresponding tetrahydrocarbylammonium tetrahydridoborates and alkali metal hydroxides.
