Public announcement on Gansu Bozhou’s annual 30,000-ton DDDA (lauric dicarboxylic acid) production project (Phase I)

Thread Content

Recently, the information regarding Gansu Bozhou’s project to produce 30,000 tons of DDDA (lauric dicarboxylic acid) per year (Phase 1) was made public on relevant websites. The total investment for the project is 1,000 million yuan, with 400 million yuan allocated to the first phase. The environmental protection costs for the first phase amount to 13 million yuan, accounting for 3.25% of the total project investment. Once completed, the project will be able to produce 30,000 tons of lauric dicarboxylic acid per year. It is being built in two phases; the first phase involves constructing a production line capable of producing 10,000 tons of DDDA per year, along with the necessary supporting facilities. Long-chain dicarboxylic acids generally refer to aliphatic dicarboxylic acids with ten or more carbon atoms in their carbon chains. Dicarboxylic acids with different numbers of carbon atoms have distinct applications: for example, sebacic acid, which has ten carbon atoms, is mainly used in the production of polyamide 610, sebacamide, polyamide 1010, the plasticizer dioctyl sebacate (DOZ), as well as lubricants and oils. It can also be utilized in the pharmaceutical industry and in the production of capacitor electrolytes ； Dodecane-based DC12 (lauric dicarboxylic acid) can be used to produce polyamide 612, high-quality fragrances, premium lubricants, advanced rust inhibitors, high-grade powder coatings, hot melt adhesives, synthetic fibers, and other polymers. Furthermore, long-chain dicarboxylic acids are gradually showing special roles and applications in areas such as the synthesis of pharmaceutical intermediates. Lauroic acid (English name: DDDAuric Acid, abbreviated as DDDA). DDDA refers to aromatic saturated dicarboxylic acids with a straight carbon chain of twelve atoms; it is an important class of fine chemical intermediates that are widely used in the synthesis of a range of high-value specialty products such as special nylons, fragrances, hot-melt adhesives, high-quality lubricants, and pharmaceuticals, making them highly versatile in application. Abroad, chemical synthesis is the primary method, with major companies including DuPont in the United States, Invista, Degussa in Germany, and Ube Industries in Japan. The domestic market includes companies such as Kaissai Biology, Hanlin, Ningxia Hengli, Shengnuoxin (Dacheng Biology), Qingjiang Petrochemical, Baiyiyuan, as well as Federal Pharmaceutical and Jiangsu Zhongzheng.
