Lithium stearate(CAS: 4485-12-5)

Lithium stearate is a white, crystalline solid with a molecular weight of approximately 494.5 g/mol. It has limited solubility in water but is soluble in many organic solvents. Chemically, it is moderately reactive, particularly in the presence of acids. It is used as a lubricant, a soap, and as a stabilizer in polymers.

Lithium stearate is typically synthesized by the reaction of stearic acid with lithium hydroxide in aprotic solvents. The process involves heating the reactants under an inert atmosphere to promote the esterification and subsequent saponification reactions, leading to a high yield of lithium stearate with good selectivity.

Lithium stearate is widely used in various industries, including the pharmaceutical industry for drug formulation, the polymer industry as a lubricant and stabilizer, and in sensors and semiconductors for its lubricating and protective properties.

When handling lithium stearate, appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. It should be stored in a cool, dry place away from acids and moisture to prevent degradation. In case of spills, they should be cleaned up immediately using appropriate spill kits, and the area should be well-ventilated. For detailed safety information, refer to the Safety Data Sheet (SDS).
