Abstract

Boron hydrides, e.g. diborane (B2H6), tetraborane (B4H10), pentaborane (B5H9), hexaborane (B6H10) and decaborane (B10H14) are made by reacting a boron halide with a hydride of an alkali or alkaline earth metal heated to 150-400 DEG C. and separating, e.g. by condensation and fractional distillation, the boron hydrides formed from the other products of reaction. The boron halide may be employed in vapour form mixed with hydrogen or inert gases such as nitrogen, helium, argon or krypton. Mixtures of boron halides and mixtures of the metal hydrides may be used, and the metal hydrides may be mixed with an alkali metal, an alkaline earth metal, magnesium, zinc or aluminium. An unstable compound, diboranemonochloride is formed during the reaction. Specification 623,761 is referred to.
