Descripción

General description

Lithium hydroxide monohydrate is a hydrate of alkali metal hydroxide. Its IR spectral analysis has been reported. A refinement of its crystal structure has been described. Its crystals belong to the monoclinic crystal system having space group C2/m. It can be prepared by reacting Li metal with H₂O, followed by the evaporation of the aqueous solution. It can be also be obtained from the basic aqueous solution of LiOH, via crystallization.

Application

Lithium hydroxide monohydrate (LiOH.H₂O) may be employed as a catalyst for the melt transesterification of diphenyl carbonate and bisphenol A. Kinetics of this transesterification reaction have been investigated.

Other Notes

Reagent for the decomposition of oxides and silicates
