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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

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).
