Dodecanedioic acid (DC12/DDDA) is the main raw material of nylon 612 and is widely used in many fields.

Dodecanedioic acid is also called dodecanedioic acid and lauric acid, abbreviated as DC12 and DDDA. Its general structural formula is HOOC (CH2) 10COOH, which refers to a linear aliphatic dibasic acid containing 12 carbon atoms in the carbon chain. . Dodecanedioic acid appears as white powder or flaky crystals, has no special odor, is soluble in organic solvents such as ethanol, and is slightly soluble in water. Dodecanedioic acid has the characteristics of low toxicity, good thermal stability, and non-corrosion. It is widely used in many fields such as plasticizers, powder coatings, high-grade rust inhibitors, lubricants, nylon 612 (PA612), and hot melt adhesives.

The synthesis methods of dodecanedioic acid include biological fermentation and chemical synthesis. Biological fermentation method refers to using fatty acids or alkanes as base materials to obtain finished products through fermentation. This method has the advantages of low production cost, simple production process, green and environmental protection, and is expected to become the mainstream synthesis method of dodecanedioic acid in the future; chemical synthesis method is based on Butadiene is used as the raw material, and the finished product is obtained through processes such as cyclization trimerization, hydrogenation, and oxidation. This method has problems such as poor quality of the finished product, many by-products, and high production costs, and is not suitable for large-scale production.

According to the “2023-2028 Dodecanedioic Acid (DC12/DDDA) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center 》shows that dodecanedioic acid is the main raw material of nylon 612. Nylon 612, also known as polyamide 612, has the characteristics of good dimensional stability, small relative width, and low density. It is widely used in mechanical processing, automobile manufacturing, household appliances and other fields. In recent years, as the market demand for long carbon chain nylon continues to grow, nylon 612, as a subdivided product, has seen increasing industry prosperity. Against this background, my country’s dodecanedioic acid market space has further expanded.

Dodecanedioic acid is also widely used in many fields such as plasticizers, powder coatings, high-grade rust inhibitors, lubricants, and hot melt adhesives. In the field of plasticizers, dodecanedioic acid can be used as a plasticizer for cellulose acetate, polyvinyl chloride and nitrocellulose; in the field of lubricants, dodecanedioic acid can be used to lubricate gas turbines and jet engines. Oil. In the future, with in-depth research, the application scope of dodecanedioic acid will be further expanded.

Major players in the global dodecanedioic acid market include Invista, Evonik, Ube Industries, etc. my country’s dodecanedioic acid industry is highly concentrated, and Cathay Biotech is my country’s leading company, accounting for nearly 90% of the market share. Cathay Biotech uses biological fermentation to produce dodecanedioic acid, and its annual production capacity of dodecanedioic acid and tridecanedioic acid reaches 75,000 tons.

Industry analysts said that dodecanedioic acid, as a long-chain dibasic acid, has a wide range of uses and has good industry development prospects. In the future, with the accelerated development of my country’s nylon 612 industry, the application demand for dodecanedioic acid will further grow. Compared with overseas developed countries, my country’s dodecanedioic acid industry started late, but its development momentum is rapid, and the technology of local companies has reached the world’s leading level.
