TG and DSC techniques proved useful in the study of the thermal properties of lithium stearate, lithium 12-hydroxystearate and related greases. Under an inert atmosphere, the stearates decompose into the oxalate prior to the formation of the carbonate. For the related greases, oil degradation-volatilization shows a discontinuity under ambient conditions, because of oxidation and carboxylic acid formation. The atmosphere and the concentration of the soap affect the chemical kinetics of thermal decomposition of the stearates and the greases.

Use of Lithium stearate
Lithium stearate exhibits high oxidation stability and a dropping point up to around 200 °C. Most greases used today in motor vehicles, aircraft, and heavy machinery contain lithium stearates, mainly Lithium stearate.[1] Greases can be made with the addition of several different metallic soaps. Some greases are prepared from sodium, barium, lithium, and calcium soaps. Lithium soap greases are preferred for their water resistance, and their oxidative and mechanical stability. Depending on the grease, they also have good performance at high or low temperatures, but not both.

Production of Lithium stearate
To produce Lithium stearate, lithium hydroxide and the fatty acid are combined in an aqueous medium. With vigorous stirring, dilute monohydrate lithium hydroxide is gradually added to a dispersion of the fatty acid in water heated to slightly below boiling.[2] Since these lithium soaps are difficult to filter, they are collected by spray drying. For applications, Lithium stearate is usually dispersed in synthetic oils such as silicone oil and ester oil. The synthetic oils are preferred for their greater stability and ability to perform at extreme temperatures.

The 12-hydroxystearic acid is prepared by the hydrogenation of castor oil.[3] After primary reaction of the saturation of most of the double bonds, dehydration and reduction of the hydroxyl group leads to the stearic acid. Hydrogenated castor oil results in a mixture of 12-hydroxystearic acid and stearic acid.

Lithium stearate is a fatty acid salt commonly known as a “lithium soap”. It is the most common soap used to stabilize and thicken lubricating greases. Lithium salts are generally preferred to soaps with other counterions such as sodium, calcium, and barium.

Using quantum mechanical calculations and molecular dynamics simulations, the authors found that the lithium salt formed the most efficiently packed aggregates. This finding is consistent with the compound’s relatively high melting temperature and the high frequency of hydroxyl hydrogen bonding in its aggregates.

According to the authors, these results “may be a factor that makes greases produced from Lithium stearate exhibit higher performance.”

Metal Soap Lithium Stearate LiO2C (CH2) 16CH3 is used for various purposes in various industries.

The main usage areas of Lithium Stearate are as follows;

- It is used as a lubricant and mold release agent in applications requiring high operating temperatures in the plastic industry.
- Used as a lubricant in grease oil production.
