Furthermore, the present invention provides the following novel first and second processes for producing 2,4,4,4-tetrafluoro-1-butene and (E)- and (Z)-1,1,1,3-tetrafluoro-2-butenes. The first process is a process for producing 2,4,4,4-tetrafluoro-1-butene by heating 1,1,1,3,3-pentafluorobutane at from about 200° C. to about 700° ... 05/18/06 - 20060106263 - Processes for production and purification of hydrofluoroolefins Disclosed herein are processes for the production of hydrofluoroolefins by dehydrofluorination. Also disclosed herein are processes for separation of hydrofluoroolefins from hydrofluorocarbons and from hydrogen fluoride. ... 05/04/06 - 20060094911 - Noncatalytic manufacture of 1,1,3,3,3-pentafluoropropene from 1,1,1,3,3,3-hexafluoropropane 1,1,3,3,3-Pentafluoropropene (CF3CH═CF2, HFC-1225zc) can be produced by pyrolyzing 1,1,1,3,3,3-hexafluoropropane (CF3CH2CF3, HFC-236fa) in the absence of dehydrofluorination catalyst at temperatures of from about 700° C. to about 1000° C. and total pressures of about atmosphere pressure in an empty, tubular reactor, the interior surfaces of which comprise materials of construction resistant ... 11/03/05 - 20050245773 - Processes for synthesis of 1,3,3,3-tetrafluoropropene Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene that comprises, in one preferred embodiment, providing a compound of the formula CF3CH2CHFX, wherein X is a selected from the group consisting of chlorine, bromine and iodine, and exposing said compound to reaction conditions effective to convert said compound to 1,3,3,3-tetrafluoropropene. ... 07/28/05 - 20050165260 - Process for producing 1,1-difluorovinyl cycloaliphatic compounds This invention relates to a process for the preparation of 1,1-difluoroolefins, e.g., difluorovinyl cycloaliphatic compounds such as difluorovinylcyclohexane and derivatives by the dehydrofluorination of a trifluoromethyl-substituted cycloaliphatic compound and the resulting compositions. This method utilizes a “sterically hindered super-base” system represented by the formula M+−NRR−; where M is Na or ... ### FreshPatents.com Support |
