The ceremony for the production of the first phase of the production of the 10,000 tons of long chain dibasic acid production line and the start of the second phase of the project using the biosynthesis method was held in Laiyang City, Shandong Province, which marked the realization of this scientific research achievement that the scientific and technical personnel of our country had invented after decades of research. Industrial production.
Long-chain dibasic acid is the main raw material for synthesizing high-grade nylon engineering plastics, hot-melt adhesives, paints and spices and other dozens of high-grade chemical products. This technology has long been monopolized by western developed countries. However, chemical synthesis methods are used in Western countries, and the production process is complex, inflammable and explosive, and expensive. The two generations of scientists represented by the Chinese Academy of Sciences’ Microbiology Research Fellow Fang Xinfang and researcher Chen Yuantong have, after decades of research, invented a bio-fermentation method for the production of long-chain dibasic acids with a simple production process, low cost, and no pollution, and won the country in 2006. Second prize for scientific and technological progress.
In 2008, this result was settled in Laiyang, Shandong, and Shandong Haolin Biotechnology Co., Ltd. invested 3 billion yuan. It plans to build a long-chain dicarboxylic acid production line with an annual output of 60,000 tons within 5 years. The first-phase project of investing nearly RMB 1 billion in long-chain dicarboxylic acid with an annual output of 10,000 tons started construction in October last year and was completed and put into production in August this year. On September 27, authoritative experts in this field in China gathered at Laiyang production site to conduct on-site technical appraisal. Experts believe that the project has adopted the most advanced bacterial strain technology at home and abroad, selected energy-saving, high-efficiency equipment, applied innovative technology, and its biological production of long-chain dicarboxylic acid industrialization technology ranks first in the world.
On September 27, the second phase of the long-chain dicarboxylic acid project with an investment of 1 billion yuan and an annual output of 20,000 tons was officially started. After the project is fully put into production, Hanlin Biotech Co., Ltd. will become the largest enterprise in the world to produce long-chain dicarboxylic acid using biological fermentation.
