Your participation in the discussions serves as the greatest motivation. ********************** [Ten Years of Great Development in Chemical Equipment] This is a continuously updated compilation thread; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On December 31, 2024, a new technology developed by a team led by Academician Liu Zhongmin from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, in collaboration with Shenhua Ningxia Coal Industry Group Co., Ltd., for producing 1,2-dichloroethane from ethylene glycol, successfully passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. 　　The evaluation committee, headed by Academician He Mingyuan from East China Normal University, Academician Xie Kechang, former vice president of the Chinese Academy of Engineering, and Academician Duan Xue from Beijing University of Chemical Technology, unanimously agreed that this achievement is highly innovative, with a technical approach that is unique at the international level. They recommended accelerating the industrial demonstration and widespread application of this technology. 　　It is reported that the research team has developed a new technical route for producing 1,2-dichloroethane from ethylene glycol, created highly active and selective catalysts, developed corresponding new reaction processes, designed specialized reactors, and built a pilot plant with a capacity of thousands of tons. Based on the above research, the research team carried out pilot tests on a kiloton scale, laying a technical foundation for the design of industrial production facilities. 　　This achievement enables the conversion of ethylene glycol into raw materials for polyvinyl chloride production, opening up new avenues for the improvement and upgrading of China’s traditional coal chemical industry, and it holds broad application prospects.
