Synthesis of 1H-polychlorofluorocycloolefins

The synthesis of 1H-polychlorofluorocycloolefin by the hydrodehalogenation of perchlorofluorocycloolefin containing –CCl=CCl– or –CCl=CF– group in dimethylformaide (DMF) or dimethylacetamide (DMAC) over Zn was investigated. It was found that the hydrodehalogenation of perchlorofluorocycloolefin occurred only on the C (sp2) position but not on C (sp3) position. In addition, the mechanisms of the hydrodehalogenation of perchlorofluorocycloolefin were proposed.

Method for preparing heptafluorocyclopentene by gas-phase fluorine-chlorine exchange

The invention discloses a method for preparing heptafluorocyclopentene by gas-phase fluorine-chlorine exchange. In the presence of a high-valent chromium-based catalyst obtained by the oxidation treatment of ammonium nitrate, 1H-perhalogenated cyclopentene and anhydrous hydrogen fluoride undergo gas-phase catalytic fluorine-chlorine exchange reaction to obtain a product 1,3,3,4,4,5,5-heptafluorocyclopentene. The method has the advantages of high yield and few by-products, which leads to the high selectivity of the target product 1,3,3,4,4,5,5-heptafluorocyclopentene, mostly close to 100%; therefore, the difficulty and pressure of the subsequent purification and separation of the production are greatly reduced, thereby improving the utilization rate of raw materials to some extent. The zero-pollution production of the 1,3,3,4,4,5,5-heptafluorocyclopentene can also be realized, a circulation system is used for reaction, so that materials can react fully, full use of the materials can be realized, pollution is greatly reduced, and zero-pollution of production is realized.
