【use】
The sodium or potassium salt of oleic acid is one of the ingredients of soap.
Pure sodium oleate has good detergency, can be used as a surfactant such as emulsifier, and can be used to treat cholelithiasis.
Other metal salts of oleic acid can also be used in waterproof fabrics, lubricants, polishing agents, etc., and the cerium salt can be used as a rodenticide.
The application is mainly used for preparing plastic plasticizer butyl oleate or octyl oleate.
The woolen industry is used to prepare antistatic agents and lubricating softeners.
The wood industry is used to prepare water repellent paraffin emulsions.
Azelaic acid is prepared by oxidation and is a raw material of a polyamide resin (nylon).
It can also be used as pesticide emulsifier, printing and dyeing auxiliary, industrial solvent, metal mineral flotation agent, mold release agent and oil hydrolysis agent for preparing carbon paper, type paper, ball pen oil and various oleates.
As a chemical reagent, as a chromatographic comparison sample and for biochemical research, calcium, ammonia, copper, calcium, sulfur, etc. are determined.
