IPC: C01B6/00
Filed: 1953-08-17
Abstract: Borohydrides of potassium, rubidium, or caesium are produced by reacting sodium borohydride, according to the reaction: NaBH4+MeR=MeBH4+NoR, where Me is potassium, rubidium, or caesium, and R is an anion other than BH4, in a solvent for both reactants, and the solvent, the quantity thereof, and the potassium, rubidium, or caesium compound are so selected that one of the reaction products remains in solution while the other, preferably the borohydride, precipitates.  The sodium borohydride may be the crude mixture from the reaction of sodium hydride with boric anhydride, an alkyl borate, or boron fluoride, and the potassium rubidium, or caesium, compound should preferably be in a slight stoichiometric excess.  The potassium, rubidium, or caesium compound may be hydroxide, methoxide, iodide, bromide, acetate, or sulphocyanide, and depending on the relative solubilities of the reaction products, the solvent may be water, methanol, ethanol, isopropylamine, or mixtures thereof, or mixtures of isopropyl alcohol and water, ethylene diamines and methanol, or pyridine and methanol.  There are a number of specific examples (1-9) in which potassium, rubidium, or caesium compounds in solution are reacted with sodium borohydride in solution in the same solvent or not in solution.  The borohydride precipitate is separated, washed, and dried under reduced pressure at 70 DEG  C. and above.  In example 10 a mixture of potassium methoxide and sodium borohydride is washed with methanol to leave a residue of potassium borohydride.  In example 11 potassium fluoride and sodium borohydride are reacted in water to precipitate the sodium salt and leave the potassium borohydride in solution.  Specification 717,451 is referred to and the preparation of potassium borohydride by reacting sodium borohydride and potassium hydroxide in wholly aqueous solvent is disclaimed.
