Stearic acid, also known as octadecanoic acid, produced by oil hydrolysis, mainly for the production of stearate. Each gram is dissolved in 21ml ethanol, 5ml benzene.
Stearic acid are widely used as the basic raw materials of surfactants. Used as lubricant and stabilizer in plastics industry; Softener and fungicide in textile industry and household detergents; It is used as wax model in precision casting and soap base in grease industry.
4.Physicochemical Properties: pure product is white with a shiny soft small pieces, melting point 69.6 degrees, the boiling point of 376.1 degrees. Relative density 0.9408, refractive index 1.4299, slowly volatile in the 90-100 degrees. Slightly soluble in cold water, soluble in alcohol, acetone, soluble in benzene, chloroform, ethyl ether, carbon tetrachloride, carbon disulfide, toluene and so on.
5.Uses Mainly for the production of stearic acid salts: Widely used system for cosmetics, plastic cold-resistant plasticizer, release agent, stabilizer, surfactants, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agent, softeners, pharmaceuticals, and other organic chemicals.
In addition, oil-soluble pigments can be used as solvents, crayons transfer slip agent, waxed paper lighting agent, stearic acid glyceride emulsifier, etc..
