l  Jiangxi Lihua Cultural Industry Co., LTD., April 22, Jiujiang Municipal Ecological Environment Bureau approved the environmental impact assessment document for the high-end fluoropolymer transformation project and made it public. The total investment of the project is 15 million yuan. After the renovation, the total capacity of the fluoropolymer unit II will remain unchanged, namely 1,000 t/a of polytrifluorovinyl chloride (PCTFE), 1,000 t/a (converted 100) of fluorocarbon resin (FEVE), 4,000 t/a (converted 100) of dispersed polytetrafluoroethylene resin (PTFE), and 500  t/a of dispersed concentrate. 1,500 t/a of suspension polytetrafluoroethylene resin (PTFE), 2,000 t/a of perfluoroethylene-propylene resin (FEP).

l  On April 27, Ningxia Baofeng Energy Storage Materials Co., LTD. Cathode, anode and electrolyte plant and the fourth phase olefin new materials project of Baofeng Energy were launched in Ningdong Energy and Chemical Industry Base, Lingwu City, Yinchuan City, Ningxia. Among them, the Baofeng Energy Storage cathode, anode and electrolyte Plant project mainly builds 250,000 tons of lithium iron phosphate cathode materials, 150,000 tons of artificial graphite anode materials, 170,000 tons of electrolyte materials (along with 20,000 t/a of lithium hexafluorophosphate (hydrogen fluoride solvent method), 260,000 t/a of carbonate, 130,000 t/a of ethylene  oxide) and other products.

l  Times Sikang New Materials Co., LTD., May 1, information from the National Intellectual Property Administration shows that Times Sikang New Materials Co., Ltd. has applied for a patent titled "A method and apparatus for preparing Sulfuryl fluoride", publication number CN119873759A, with the application date being October 2023. The application produces sulfuryl fluoride through a gas-solid reaction of gaseous sulfuryl chloride with fluoride salt powder, without the need for raw materials such as solvents and catalysts, thus reducing production costs. At the same time, a series of multi-stage reactors is used to achieve continuous reaction, thereby increasing the purity of thioyl fluoride.

l  Zibo Municipal Ecology and Environment Bureau accepted and made public the environmental impact assessment document for the 200 t/a tetrafluoropropylene pilot project of Shandong Dongyue Green Cold Technology Co., Ltd. on May 6. The project, with a total investment of about 37 million yuan, will build a 200 t/a pilot-scale facility for tetrafluoropropylene.

l  Fujian Jianyang Jinshi Fluorine Industry Co., Ltd. obtained a patent titled "A Method for the Preparation of Hexafluorobutadiene" on May 13, with the authorization announcement number CN116768695B and the application date being June 2023. The invention, compared with the existing technology, uses titanium dioxide loaded on molecular sieves as the catalyst to catalytically pyrolyze trichloroethylene at high temperature to produce 3, 4-dichlorohexafluoro-1-butene, and then dechlorinated to prepare hexafluorobutadiene, which improves the selectivity and yield of hexafluorobutadiene, reduces the pyrolysis temperature, and through the selection of reactants and the control of reaction conditions, High purity hexafluorobutadiene can be produced by the method, which is simple in process and improves the preparation effect of hexafluorobutadiene.

l  Jinhua Yonghe Fluorine Chemical Co., LTD., May 16, according to information from the National Intellectual Property Administration, has obtained a patent titled "A Process for co-production of pentafluoroethane by recovering tetrafluoroethylene-difluoromethane azeotrope", with the patent announcement number CN116082118B, and the application date is January 2023. The invention provides a process for the recovery of tetrafluoroethylene-difluoromethane azeotropes to produce pentafluoroethane, which significantly reduces energy consumption and costs through multiple technical means.?
