PREPARATION OF HALOGEN AND HYDROGEN CONTAINING ALKENES OVER METAL FLUORIDE CATALYSTS

Halogenated alkenes, especially fluorinated alkenes can be prepared from halogenated and fluorinated alkanes, respectively, by dehydrohalogenation or dehydrofluorination in the presence of a high-surface metal fluoride or oxifluoride. Preferably, trifluoroethylene, pentafluoropropene, tetrafluorobutenes or trifluorobutadiene are prepared. Aluminium fluoride is highly suitable. The metal fluoride or oxifluoride can be applied supported on a carrier.

A METHOD FOR PRODUCING 4,4,4-TRIFLUOROBUTANE-2-ONE

The present invention provides a novel method for preparing 4,4,4-trifluorobutane-2-one by providing a fluorobutene selected from the group consisting of 2,4,4,4-tetrafluoro-1-butene, (E)- 1,1,1,3-tetrafluoro-2-butene, (Z)-1,1,1,3-tetrafluoro-2-butene, and mixture thereof; and reacting the fluorobutene(s) with a proton acid and water.
