Usage:
1. Used as cold plasticizers, resins and nylon and other raw materials
2. Used as analytical reagent
3. Mainly used sebacic acid ester plasticizer and nylon mold resin raw materials, can also be used as raw materials for high temperature lubricants. The main ester products are methyl ester, isopropyl ester, butyl ester, octyl ester, nonyl ester and phenyl methyl ester, the usual ester is dibutyl sebacate and dioctyl sebacate. Sebacic acid plasticizer can be widely used in PVC, alkyd resin, polyester resin and polyamide molding resin, because of its low toxicity and high temperature performance, it is often used for some special purpose resin. Nylon molded resin produced with sebacic acid has a high toughness and low moisture absorption, but also processed into many special-purpose products. Sebacic acid or rubber softeners, surfactants, coatings and spices raw materials.
4. Gas Chromatography tailing agent, separation and analysis of fatty acids can be used for precipitation and quantitative determination of thorium, and thorium and cerium and other rare earth element cable separation. Plasticizers, synthetic resins and synthetic fibers.
5. For the separation and analysis of fatty acids; for gas chromatography tail reduction agent; Used as plasticizers
6.Automotive applications such as antifreeze

Details:

Sebacic acid is widely used, mainly used to make sebacic acid esters, esters widely used, such as dibutyl sebacate, sebacate dioctyl sebacate, di-isooctyl sebacate. These esters can be used for plastic, cold rubber plasticizer, can also be used to produce polyamide, polyurethane, alkyd resin, synthetic lubricants, lubricants additives and spices, paints, cosmetics and so on. Also can be used for the production of nylon 1010, nylon 910, nylon 810, nylon 610, nylon 9 and high temperature lubricating oil raw materials diethylhexyl ester. It is also used in the production of alkyd resins (used as surface coatings, plasticized nitrocellulose and urea resin varnishes) and as plasticizers, softeners and solvents for polyurethane, cellulose, vinyl and elastomers. raw material.

Brief manufacture process:
The castor oil as raw material, the ricinoleic acid which is separated from caustic soda in the pressurized and 280 ~ 300 ° C under alkaline melting, heating reaction 10h, can be obtained sodium salt of sebaceous acid, and by-product 2- Octanol. The sodium salt dissolved in water, adding sulfuric acid and decolorization, the solution cooling, precipitation of sebaceous acid, washed with cold water, and finally recrystallization.
