Overview of Lithium Stearate

Lithium stearate is a chemical substance, also known as lithium octadecanoate, white powder, or colorless crystal. Density: 1.025 g/cm3. Melting point: 220.0-221.5°C. Stable under normal temperature and pressure. Slightly soluble in water and ethanol, the solubility in water is 0.09 g/100ml, and the solubility in ethanol is 0.04 g/100ml. It is decomposed into stearic acid and corresponding lithium salt in case of strong acid. Insoluble in ethyl acetate and mineral oil. It forms a colloid in mineral oil.

Synthesis method of lithium stearate

Method 1: Dissolve 10g stearic acid in 100mL 95% ethanol, titrate with 0.5mol/L lithium hydroxide ethanol solution (if lithium hydroxide cannot be completely dissolved in ethanol, add water to completely dissolve it), using phenolphthalein as an indicator. After the reaction reaches the equivalence point, the precipitated lithium stearate soap is separated by suction filtration. The crude product can be recrystallized with 95% ethanol to obtain a pure product.

Method 2: Dissolve sodium hydroxide in water to form a solution, add stearic acid, fully react, and heat to above 100°C. Lithium chloride is dissolved in water, cooled to normal temperature, and then added to the prepared sodium stearate solution for reaction; after the reaction, the material is discharged and centrifuged for dehydration; the finished product is dried by airflow drying equipment.

Lithium stearate has good stability and reduces the overall cost of the enterprise. Mainly used as PVC heat stabilizer, suitable for transparent products. Its good performance can reduce the overall cost of the enterprise.

Application of lithium stearate

Widely used in high-temperature lubricants.

Stabilizer for the plastics industry.

Two synthetic methods of lithium stearate

Cosmetic oils, gels, crayons, emulsifying and dispersing agents.

Corrosion inhibitor in the petroleum industry.
