Synthesis

Synthesis is by neutralization of lactic acid with lithium hydroxide:

LiOH + CH3CH(OH)COOH → CH3CH(OH)COOLi + H2O

Physical properties

Lithium lactate forms an amorphous solid.

It dissolves very well in water[6] and organic solvents.

The compound demonstrates optical isomerism.

It emits acrid smoke when heated to decomposition.[7]

Chemical properties

It reacts with triphosgene to obtain lactic acid-O-internal anhydride.[8] It can be used as a precursor to prepare Li4SiO4,[9] Li4Ti5O12/C[10] and other materials.

Use

It is part of drugs that promote the excretion of uric acid from the body.

Antipsychotic.
