Stearic acid 1810.
Stearic acid, namely octadecanoic acid, has a simple structure: CH3(CH2)16COOH, which is produced by hydrolysis of oils and fats and is mainly used for the production of stearates. Each gram is dissolved in 21 ml of ethanol, 5 ml of benzene, 2 ml of chloroform or 6 ml of carbon tetrachloride.
Stearic acid is a kind of fatty acid widely found in nature. Almost all fats and oils contain stearic acid in different amounts. It is high in animal fat, such as 24% in butter and less in vegetable oil. Tea oil is 0.8%, palm oil is 6%, but cocoa butter is as high as 34%. The production methods of industrial stearic acid mainly include two methods of fractionation and pressing. A decomposing agent is added to the hardened oil, and then the crude fatty acid is hydrolyzed, and then washed, distilled, and decolorized to obtain a finished product. At the same time by-product glycerin

Function and use.
Mainly used in the production of stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
Widely used in cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others. Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, an emulsifier for stearic acid glycerides, and the like.
The product is used as a raw material for lubricants, antifoaming agents and food additives such as stearic acid glycerides, sorbitan stearate, sucrose esters and the like in the food industry. Used as raw materials for auxiliaries and as raw materials for daily chemical products.
Stearic acid is widely used in the manufacture of PVC plastic pipes, sheets, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability. In plastic PVC pipe, stearic acid helps to prevent "coking" during processing. It is an effective heat stabilizer in the processing of PVC film, and it can prevent the finished film caused by exposure to sulfide. Discoloration.
