Abstract:
The invention relates to a process for preparing a compound of formula CF3CF═CHX, CHX2CX═CX2 or a linear or branched C4-7 (hydro)fluoroalkene, wherein each X is, independently, H or F provided that in CHX2CX═CX2 at least one X is F, which process comprises dehydrohalogenating a compound of formula CF3CFYCH2X, CF3CFHCYHX, CHX2CXYCX2H, CHX2CXHCX2Y, or a linear or branched C4-7 hydro(halo)fluoroalkane, wherein each X is, independently, H or F provided that in CHX2CXYCX2H and CHX2CXHCX2Y at least one X is F, wherein Y is F, Cl, Br, or I, in the presence of a base.
