Lead stearate is a metal-organic compound, a salt of lead and stearic acid with the chemical formula C
36H
70PbO
4.[1] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.[2]
Synthesis
The compound can be prepared by reacting stearic acid, lead oxide, and a catalyst acetic acid.[3]
Physical properties
White powder with a slight fatty odor. Sinks in water.[4]
Slightly soluble in water.[1]
Uses
The compound is used as a drier in oil paints and varnishes to speed the polymerization and oxidation processes. Also used as a lubricant and stabilizer in vinyl polymers and as a corrosion inhibitor in petroleum products.[5][6][7]
