Potassium borohydride is a kind of white loose powder or crystals, with the relative density of 1.178. Its melting point is 585 ° C, so it begins to decompose about 500 ° C in a vacuum. It is stable in the air, not hygroscopic. Potassium borohydride is soluble in water, aqueous solution is heated to 1000 ° C, complete release of hydrogen. It is soluble in liquid ammonia, slightly soluble in methanol and ethanol, and almost insoluble in ether, benzene, tetrahydrofuran, ether and other hydrocarbons. Potassium borohydride is stable in an alkaline environment in the case of inorganic acids decompose and release hydrogen. Properties of Potassium borohydride:
Melting point:> 400 ° C (decomposition)
Solubility: insoluble in hydrocarbons, benzene, ether, slightly soluble in methanol, ethanol, soluble in liquid ammonia.
Density: the relative density (water = 1) 1.18.
Stability: Stable.
Hazard markers: 10 (when wet flammable liquids).
