标题 :Process for catalytic hydrodefluorodimerization of fluoroölefins
发明人：BAKER RALPH THOMAS; SICARD ALEXANDRE JAMES
权利人:UNIV OTTAWA
摘要:The present application provides a hydrodefluorodimerization process, which is useful in the synthesis of, for example, fluoroolefins that can be used as refrigerants, blowers and the like. The process is an “early-stage fluorinationâ€? process, wherein precursors containing fluorine are assembled into the desired product using a zerovalent nickel catalyst. Also provided is a liquid composition comprising one or more fluoroolefin produced by this catalytic process.

摘要:A method of synthesizing 2,3,3,3-tetrafluoropropene (1234yf) from 2-chloro-3,3,3-trifluoropropene (1233xf). The 2-chloro-3,3,3-trifluoropropene (1233xf) is reacted in the vapor phase, in the presence of a catalyst, at a temperature and pressure sufficient to selectively convert the 2-chloro-3,3,3-trifluoropropene (1233xf) to 2,3,3,3-tetrafluoropropene (1234yf) without the use of antimony-based catalysts.

摘要:The present invention pertains to a novel process of manufacturing the compound 2,3,3,3-tetrafluoropropene (1234yf). The compound 1234yf is the newest refrigerant with zero OPD (Ozone Depleting Potential) and zero GWP (Global Warming Potential). Thus, the invention relates to a process, involving a carbene generation route, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), and optionally of the compound 2-chloro-1,1,1-trifluoropropene (1233xf) via carbene route and compound 243db (2,3-dichloro-1,1,1-trifluoropropane). The invention also relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), wherein the compound 243db (2,3-dichloro-1,1,1-trifluoropropane) serves as a starting material, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf). Further, the invention relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), and of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), the initial starting materials are selected from the group consisting of com-pound 123 (2,2-dichloro-1,1,1-trifluoroethane), compound 124 (2-chloro-1,1,1,2-tetrafluoroethane), and compound 125 (pentafluoroethane).
