General description: Lithium borohydride, a white solid, may be prepared from the exchange reaction of LiCl and sodium borohydride in isopropylamine. The orthorhombic crystal structure converts to tetragonal at 108oC and eventually melting at 278oC. Infrared and Raman spectral studies at 80oC have been reported in a study.
Application: Versatile reducing agent for aldehydes, ketones, acid chlorides, lactones, epoxides, and esters. Applied in the lithiation of 2H-WS2 giving high yields of exfoliated WS2, and opening the way to new intercalation compounds and nanocomposites. Lithium borohydride is used as hydrogen storage system. It regenerates hydrogen at 320-380oC at 10atm (H2 pressure).
