Application of stearic acid 57-11-4 Stearic acid, namely octadecanoic acid, molecular formula C18H36O2, is produced by the hydrolysis of oil and is mainly used for the production of stearate. Dissolve each gram in 21ml ethanol, 5ml benzene, 2Chemicalbookml chloroform, or 6ml carbon tetrachloride. Mainly used in the production of stearate: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
The main purpose
Stearic acid is mainly used in the production of stearate: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, stearic acid Potassium. Widely used in cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, water repellants, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals, and other organic chemicals.
In addition, Stearic acid can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a polish for wax paper, an emulsifier for glyceryl stearate, and the like. This product is used in the food industry as a lubricant, a defoamer, and a raw material for food additives such as glycerol stearate, sorbitan stearate, and sucrose ester. Stearic acid is used as the raw material of auxiliary agents and the raw material of daily chemical products. Stearic acid is widely used in the manufacture of PVC plastic pipes, sheets, profiles, and films.
Stearic acid is a heat stabilizer for PVC, which has good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent “coking” during processing, is an effective heat stabilizer in PVC film processing, and protects the finished film from exposure to sulfides discoloration.
