Description

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.
