Properties and synthesis of lithium stearate

Lithium stearate is a white powdery compound with chemical formula LiC18H35O2 and CAS registration number 4485-12-5.

Characteristics of lithium stearate

White powder or colorless crystal. Density: 1.025 g/cm3. Melting point: 220.0-221.5℃. 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. In case of strong acid, it decomposes into stearic acid and corresponding lithium salt. Insoluble in ethyl acetate and mineral oil. Forms colloids in mineral oil.

Lithium stearate synthesis method

method one:

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

Method Two:

Sodium hydroxide is dissolved in water to form a solution, stearic acid is added to it, and then fully reacted and heated to above 100°C. The lithium chloride is dissolved in water, and after it is cooled to normal temperature, it is added to the prepared sodium stearate solution for reaction; after the reaction is finished, it is released and dehydrated by a centrifuge; and the finished product is obtained by drying with an airflow drying device.

Overview of Lithium Stearate Grease Additives

Lithium stearate is stable at normal temperature and pressure, insoluble in water, ethanol and ethyl acetate. Lithium stearate can be used as a heat stabilizer for PVC and a plasticizer in combination with phthalates. The product will not produce white fog, and the transparency of the paint film is good.

Applications of Lithium Stearate Grease Additives

1) High temperature grease, with high water resistance, high temperature resistance and excellent low temperature performance;

2) Stabilizer in plastic industry, suitable for transparent products, with superior performance, which can reduce the overall cost of enterprises;

3) Grease, gelling agent, crayon, cosmetic emulsifying and dispersing agent;

4) Corrosion inhibitor in petroleum industry.

5) Stabilizers, lubricants, corrosion inhibitors, positive electrode material additives for alkaline zinc-manganese batteries in the petroleum industry, etc.

6) Used as high temperature lubricant and stabilizer, plastic industry stabilizer, etc.

7) Metal powder lubricant.
