Description of Sebacic acid

Sebacic acid is a naturally occurring dicarboxylic acid with the structure (HOOC)(CH2)8(COOH).
In its pure state it is a white flake or powdered crystal. The product is described as non-hazardous, though in its powdered form it can be prone to flash ignition (a typical risk in handling fine organic powders).
Sebaceus is Latin for tallow candle, sebum is Latin for tallow, and refers to its use in the manufacture of candles. Sebacic acid is a derivative of castor oil, with the vast majority of world production occurring in China which annually exports over 100,000 metric tonnes, representing over 90% of global trade of the product.; In the industrial setting, sebacic acid and its homologues such as azelaic acid can be used as a monomer for nylon 610, plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. Sebacic acid is also used as an intermediate for aromatics, antiseptics, and painting materials.
Sebacic acid is produced from castor oil by using sodium hydroxide, sulfuric acid with catalysts including zinc oxide and phenol. Byproducts include glycerol, octanol and polymer residue.

What is Sebacic acid?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product isSebacic acid which has developed particularly rapidly in recent years. Do you know aboutSebacic acid?


The official answer: Decanedioic acid (English name Decanedioicacid) also known as n-decanedioicacid (n-decanedioicacid) 1,10-decanedioic acid (1,10-decanedioic acid), 1,8-octanedicarboxyli cacid (1,8-octanedioic acid), sebacic acid ( Sebacicacid). Sebacic acid is an aliphatic dibasic acid and is found in roasted tobacco, white tobacco, and spice tobacco. At room temperature, sebacic acid is white flaky crystals, and the industrial product is slightly yellow. Slightly soluble in water, insoluble in benzene, petroleum ether, carbon tetrachloride, easily soluble in ethanol and ether. Sebacic acid is flammable, low toxicity. Harmful by mouth, irritating to eyes, respiratory system, and skin. Made from natural castor oil or adipic acid monoesters, it is mainly used to make esters of sebacic acid, whose esters are widely used. The molecular formula of sebacic acid is C10H18O4, and the chemical structure formula is HOOC(CH2)8COOH.

What’s the application of Sebacic acid?

Sebacic acid is widely used to make esters of sebacic acid. Its esters are widely used, such as dibutyl sebacate, dioctyl sebacate, and dioctyl sebacate. These esters can be used as plasticizers for plastics and cold-resistant rubber, and also used to make polyamides, polyurethane, alkyd resins, synthetic lubricants, lubricant additives, as well as fragrances, coatings, and cosmetics. They are also used as raw materials for the production of nylon 1010, nylon 910, nylon 810, nylon 610, nylon 9, and diethylhexyl ester for high-temperature resistant lubricants. It is also used as raw material for the production of alkyd resin (used as surface coating, plasticizing nitrocellulose coating, and urea resin varnish) and polyurethane rubber, cellulose resin, vinyl resin and plasticizer, softener, and solvent for synthetic rubber.

Manufacturing methods: sebacic acid was first obtained by dry distillation of castor oil with alkali, later developed synthetic methods, and is currently developing a new route for the fermentation of petroleum n-alkanes to sebacic acid. Another production method of sebacic acid is the electrolytic oxidation method of adipic acid developed by Asahi Kasei Industries, Japan, which is not produced on a large scale because of the higher cost compared with the castor oil alkali decomposition method.

(1) castor oil cracking method: castor oil is heated under the action of alkali hydrolysis to generate ricinoleic acid sodium soap, then add sulfuric acid to generate ricinoleic acid; in the presence of diluent cresol, add alkali heated to 260-280 ℃ for cracking, generating sebacic acid bis-sodium salt and secoctanol and hydrogen, cracked material diluted by water, heated and neutralized with acid, the bis-sodium salt into monosodium salt; then decolorized with activated carbon, boiling the neutralization solution Add acid to make sebacic acid monosodium salt into sebacic acid crystal precipitation, and then separated and dried to get the finished product. Raw material consumption quota: castor oil (industrial product) 2100kg/t, sulfuric acid (98) 1600kg/t, caustic soda (95) 1200kg/t, cresol (industrial product) 100kg/t.

(2) Petroleum n-decane fermentation method: Using 200# solvent oil or n-decane made by separation in 166-182℃ fraction, sebacic acid can be made by fermenting with 19-2 lipolytic pseudo-serum yeast.

(3) New cyclopentanone method: using palladium salt – copper or iron as a catalyst, in the solvent of ethanol, propanol or other alcohols, under the moderate conditions of low temperature and atmospheric pressure at 40-60℃, cyclopentene is oxidized with air to generate cyclopentanone, and then oxidized and dimerized with an iron catalyst to make sebacic acid.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
