Most lithium-based greases are prepared from 12-hydroxystearate soap

Overview of Lithium 12-hydroxystearate

Lithium 12-hydroxystearate (C18H35LiO3) is a compound belonging to the lithium soap class. In chemistry, "soap" refers to a salt of fatty acids. Lithium 12-hydroxystearate is a white solid. Lithium soap is an important component of many greases. Lithium 12-hydroxystearate is a fatty acid salt commonly referred to as "lithium soap".It is the most common soap used to stabilize and thicken greases. Lithium is usually preferable to soaps with other counterweight ions, such as sodium, calcium, and barium.

Lithium 12-hydroxy stearic acid is widely considered as the preferred fatty acid in the thickening agent of lithium base grease. The fatty acid has also been used as a thickener for calcium-based greases. Fats prepared with this acid usually have a smooth, buttery texture. Calcium 12-hydroxystearate grease is one of the most common types of anhydrous calcium-based grease. It has a drop point of approximately 275 to 300 degrees Fahrenheit, a maximum usable temperature of approximately 230 degrees Fahrenheit, and has average properties at low temperatures.

To produce lithium 12-hydroxystearate, lithium hydroxide is combined with a fatty acid in an aqueous medium. By vigorous stirring, the diluted monohydrate lithium hydroxide is gradually added to the fatty acid dispersion, heating the water to just below the boiling point. Since these lithium soaps are difficult to filter, they are collected by spray drying. For applications, lithium 12-hydroxystearates are usually dispersed in synthetic oils such as silicone oils and ester oils. Synthetic oils are favored for their greater stability and performance at extreme temperatures.

Using castor oil as raw material, 12-hydroxy stearic acid was prepared by hydrogenation. After the first reaction, most of the double bonds are saturated and the hydroxyl group is dehydrated and reduced leading to the formation of stearic acid. The result of hydrogenation of castor oil is a mixture of 12-hydroxy stearic acid and stearic acid.

Application of Lithium 12-hydroxystearate

Lithium 12-hydroxystearate is a fatty acid salt commonly known as "lithium soap".It is most commonly used to stabilize and thicken the greases of soap. Lithium is often preferred over soaps containing other counterions, such as sodium, calcium and barium.

Most lithium-based greases are made from 12-hydroxystearate soap, which has many functions. These greases have a higher drop point, about 350-400 degrees Fahrenheit.

Lithium 12-hydroxystearate has high oxidation stability with a melting point of about 200°C. Most greases used in motor vehicles, aircraft, and heavy machinery today contain lithium stearate, primarily lithium 12-hydroxystearate. Grease can be made by adding several different metallic soaps. Some oils are made from soaps of sodium, barium, lithium, and calcium. Lithium soap grease is favored for its water resistance, oxidation and mechanical stability. Depending on the grease, they also perform well at high or low temperatures, but not both.

They also have good water resistance, although the grease may soften and runoff in the presence of large amounts of water. The maximum usable temperature is approximately 250 degrees Fahrenheit, which is better than or equal to most other types of greases. Unlike calcium 12-hydroxystearate, lithium 12-hydroxystearate has poor compatibility with other greases.
