From 2005, Hebei Hengshui Jinghua Chemical Plant invested more than 9.8 million yuan in technical research on high-quality sebacic acid production technology and achieved success with the assistance of Beijing University of Chemical Technology, Tsinghua University and Tianjin University. The products produced by the new process have the characteristics of environmental protection, non-toxicity, high temperature resistance, and oil resistance. The purity of the product is more than 99.5%, and the ash content and moisture content are only 0.015% and 0.1%, which is 40% and 60% lower than the national standard. It can fully meet the needs of high-end users in the international market.
It is understood that in Hebei Hengshui Jinghua chemical plant in terms of technological innovation, first through the development of automatic decolorization of new technology activated carbon, the product impurity T content is lower than 10 × 10-6; second is to develop a three-stage decolorization and intermediate pretreatment new process , to further reduce the production of azelaic acid color number, to meet the requirements of high-quality sebacic acid products; third is to adopt a large number of new technologies such as automated washing, new processes, so that production costs than similar foreign products decreased by 20% , With greater cost advantages.
According to the company's scientific research personnel, with the completion of the second azelaic acid production line, the current production of high-quality sebacic acid products has completely met the needs of a series of high-end users such as high-temperature lubricants and nylon 1010. Based on its 70% share of the Japanese market, the product has recently signed supply contracts with customers in Europe, the United States and other countries. The export ratio of products has accounted for more than 70% of production.
High-quality sebacic acid achieves scale production
On May 11th, the reporter learned from an interview with Hengshui Jinghua Chemical Plant in Hebei that the second azelaic acid production line built with the plant’s investment of RMB 242 million has been successfully put into production, and its high-quality sebacic acid production capacity has reached 40,000 tons. China's sebacic acid products have entered the world's advanced ranks on the scale of production. At the same time, they have also achieved new breakthroughs in technology and technology.
