Lithium borohydride is a kind of inorganic compound, chemical formula LiBH4, is a white crystalline powder, insoluble in hydrocarbons, benzene, ether, liquid ammonia. The aqueous solution is easily hydrolyzed by heating, and the acid reaction is rapid. Used as hydrogen production raw material and organic synthesis reducing agent. It is hygroscopic. Stable in dry air and decomposes in wet air. Used as a reducing agent for hydrogen sources and organic groups. Commercially used for bleaching wood pulp and electroplating without electricity. Lithium borohydride is one of the most important reducing agents in organic chemistry and belongs to the borohydride family of compounds. Lithium borohydride can regulate its reduction ability by using different solvents, has good chemical selectivity, and can even complete the reaction at low temperatures.
