Abstract
The present invention provides novel compounds 2,4,4,4-tetrafluoro-1-butene and (E)- and (Z)-1,1,1,3-tetrafluoro-2-butenes. 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° C. The second process is a process for producing (E)- and (Z)-1,1,1,3-tetrafluoro-2-butenes by bringing 1,1,1,3,3-pentafluorobutane with a base. By the first and second processes, it is possible to obtain respective target fluorobutenes with high selectivity.
Claims7
A process for producing 2,4,4,4-tetrafluoro-1-butene, comprising heating 1,1,1,3,3-pentafluorobutane at from about 200° C. to about 700° C.
A process for producing 2,4,4,4-tetrafluoro-1-butene, comprising that 1,1,1,3,3-pentafluorobutane is passed through a reaction tube heated at 400° C.-500° C. under a condition that is substantially free of a base.
