On December 10, 2024, a signing ceremony for the commercialization of this technology was held at Jilin University of Chemical Technology. Commissioned by Daqing Zhonglan Petrochemical Co., Ltd., the university developed a new, environmentally friendly, and efficient process for the production of tert-dodecyl mercaptan. 　　Dodecyl mercaptan is a key additive in the synthesis of polymer materials such as butadiene styrene rubber and acrylonitrile-butadiene-styrene (ABS) resin; it is primarily used as a degree-of-polymerization regulator to reduce the branching of polymer chains and achieve a uniform molecular weight distribution. Traditional domestic preparation methods suffer from issues such as outdated technology, high costs, and significant pollution. 　　To address this challenge, a research team led by Zhang Jibo and Liu Zhigang from Jilin University of Chemical Technology made innovative breakthroughs in the synthesis process of dodecyl mercaptan after prolonged efforts. This process uses a homogeneous fixed-bed reaction system in place of the traditional tubular trickle-bed system, improving the controllability and efficiency of the reaction process while significantly reducing its environmental impact. During the pilot scale phase, team members conducted thorough testing and optimization of the manufacturing process to ensure the quality and stability of the product; the pilot test was successfully completed on July 18, 2024, paving the way for the pilot production and industrialization stages. 　　Ai Xuezhong, president of Jilin University of Chemical Technology, stated that the university will take this signing as an opportunity to continue leveraging its role as a key link in driving innovation, serving as a primary source of talent, and functioning as an essential element in scientific and technological development. By focusing on strategic planning, it will effectively integrate resources related to talent recruitment, scientific research, and the transformation of research results, thereby promoting coordinated development among the innovation chain and industrial chain and fostering progress through high-level scientific and technological innovation.
