摘要：The present invention provides novel compounds, 2,4,4,4-tetrafluoro-1-buteneand (E)- and (Z)-1,1,1,3-tetrafluoro-2 butenes. Furthermore, the present inventionprovides the following novel first and second processes for producing 2,4,4,4-tetrafluoro-1-butene, (E)- and (Z)-1,1,1,3-tetrafluoro-2-butenes, and 1,1,3-trifluorobutadiene. The first process is a process for producing 2,4,4,4-tetrafluoro-1-butene by heating 1,1,1,3,3-pentaflurobutane at from about 200° C. to about 700° C. Thesecond process is a process for producing (E)- and (Z)-1,1,1,3-tetrafluoro-2-butenes bybringing 1,1,1,3,3-pentafluorobutane with a base. By the first and second processes, it ispossible to obtain respective target fluorobutenes with high selectivity. In third to fifthprocesses, 2,4,4,4-tetrafluoro-1-butene, (E)- and (Z)-1,1,1,3-tetrafluoro-2-butene, and1,1,3,-trifluorobutadiene can be produced by heating 1,1,1,3,3-pentafluorobutane in thepresence of a catalyst. This catalyst can be regenerated by the contact with a halogen-containing gas in sixth process.
