Product Description
Lithium stearate, also known as lithium octadetanate, is an organolithium compound. The pure product is a white crystalline powder with a density of 1.025 and a melting point of 220°C; the ordinary product is often slightly yellow and has a low melting point. Slightly soluble in water, soluble in hot ethanol, decomposed by strong acid to form stearic acid and corresponding lithium salts. This substance is mainly used as a heat stabilizer for plastics, a grease temperature resistant, and a paper coating.
The preparation method is as follows: molten stearic acid is reacted with dilute sodium hydroxide solution to form a dilute soap solution, and then metalysis with lithium chloride.
Density: 1.025
Melting point: 220°C

Solubility: slightly soluble in water, soluble in heatethanol。
Preparation or source: to be moltenSteroesteric acidWith sparseness sodium hydroxideThe solution is made into a thin soap solution, and then it is added Lithium chloride It works.
Note: Ordinary is a slightly yellowish powder with a low melting point.
Lithium stearate uses:
- Powder metallurgy lubricants
- High temperature lubricants
- Corrosion inhibitor for the petroleum industry
- Thickener and gelling agent
- Lubricant additive, active ingredient in lithium-based grease
- Stabilizer in plastic and rubber products.
FAQ - Technical & Supply Chain

Q:
Does Lithium Stearate correspond to the standard 12-hydroxystearate thickener or the pure stearic acid salt?
A: Lithium Stearate is verified under CAS 4485-12-5 as the specific salt of stearic acid (Octadecanoic acid), distinguishing it from Lithium 12-hydroxystearate to ensure the correct gelling properties and thermal stability profile for general-purpose lithium greases. -
Q:
What is the primary functional contribution of Lithium Stearate in lubricant production?
A: Lithium Stearate is typically applied as a gelling agent to transform liquid oils into semi-solid greases, providing the final product with excellent structural shear stability and resistance to water washout.
