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:In this invention we are disclosing a process for the synthesis of hydrocchlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the steps of fluorination of hydrochloropropenes or hydrochloropropanes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, catalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes.

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.
