After two months of installation, commissioning and careful deployment of the device, Shanghai Huayi Sanaifu New Materials Co., Ltd. (hereinafter referred to as "Shanghai Huayi Sanaifu") F113 hydrogenation CTFE test device was successfully opened, and the whole process of hydrogenation was successfully opened. The product quality monitoring of each point of the device was qualified, and the device was connected. The continuous operation is smooth, and the catalyst performance index reaches the expected goal.

The successful start of the test device marks that Shanghai Huayi Sanaifu has mastered the key technology of the new hydrogenation CTFE process through independent research and development, laying a solid foundation for the industrialization of the new process. The technology is jointly developed by the Central Research Institute of Shanghai Huayi Group and Shanghai Huayi Sanaifu. The project catalyst test and reaction process development will be completed in 2021, the amplification and molding of the catalyst, the evaluation of the original particle catalyst and the design of the test device will be completed in 2022, and the test will be launched at Shanghai Huayi Sanaifu Changshu Base. Inspection device construction work. The project gives full play to the technical advantages of the Central Research Institute of the Group, takes enterprises as the main body of innovation, and actively promotes the implementation of industrialization, which will help Shanghai Huayi Sanaifu to continue to consolidate and enhance the market competitiveness and industry status of CTFE and its downstream products.

Trifluorochlorofluoroethylene, referred to as CTFE, molecular formula C2ClF3, is one of the important fluorinated olefins. Shanghai Huayi Sanaifu is a well-known supplier of fluorine chemicals in the industry, and the "four fluoroolefins" are all produced. The fluorine-containing polymer material formed by CTFE homogenization of polytrifluorochloroethylene (PCTFE) or CTFE copolymerization with other olefins has excellent mechanical processing properties, unique electrical properties and heat resistance and chemical corrosion resistance. It is widely used in cutting-edge technology, military aerospace and electronics industry and other fields. In addition, as a chemical intermediate raw material, CTFE can also be used for the synthesis of downstream high value-added fluorine-containing chemicals.

At present, the mainstream route for synthesizing CTFE is the zinc powder process, but there are problems such as high single consumption of zinc powder, large solvent use and difficult treatment of zinc powder waste residue. The hydrogenation method adopts a fixed bed continuous reaction process, which is easy to achieve large-scale and continuous production. It has significant technical and cost advantages. The core of its technology lies in the development of high-performance hydrogenation catalysts.
