Abstract: The disclosure relates to a method for hydrofluorination of an olefin of the formula: RCX═CYZ to produce a hydrofluoroalkane of formula RCXFCHYZ or RCXHCFYZ, wherein X, Y, and Z are independently the same or different and are selected from the group consisting of H, F, Cl, Br, and C1-C6 alkyl which is partially or fully substituted with chloro or fluoro or bromo; and R is a C1-C6 alkyl which is unsubstituted or substituted with chloro or fluoro or bromo, comprising reacting the olefin with HF in the liquid-phase, in the presence of SbF5, at a temperature ranging from about −30° C. to about 65° C. and compositions formed by the process.

Abstract: This disclosure relates to processes which involve: contacting a mixture comprising at least one fluoroolefin and at least one impurity with at least one zeolite to reduce the concentration of the at least one impurity in the mixture; and the at least one zeolite is selected from the group consisting of zeolites having pore opening of at least 4 Angstroms and no more than about 5 Angstroms, zeolites having pore opening of at least about 5 Angstroms and Sanderson electronegativity of no more than about 2.6, and mixtures thereof; provided that the at least one zeolite is not zeolite 4A. This disclosure also relates to processes for making at least one hydrotetrafluoropropene product selected from the group consisting of CF3CF═CH2, CF3CH═CHF, and mixtures thereof; and relates to processes for making at least one hydrochlorotrifluoropropene product selected from the group consisting of CF3CCl═CH2, CF3CH═CHCl, and mixtures thereof.

Abstract: This disclosure relates to processes which involve: contacting a mixture comprising at least one fluoroolefin and at least one RfC≡CX impurity with at least one zeolite to reduce the concentration of the at least one RfC≡CX impurity in the mixture; wherein Rf is a straight-chain perfluorinated alkyl group, and X is H, F, Cl, Br or I; and the at least one zeolite is selected from the group consisting of zeolites having pore opening of at least 4 Angstroms and no more than about 5 Angstroms, zeolites having pore opening of at least about 5 Angstroms and Sanderson electronegativity of no more than about 2.6, and mixtures thereof; provided that the at least one zeolite is not zeolite 4A. This disclosure also relates to processes for making at least one hydrotetrafluoropropene product selected from the group consisting of CF3CF═CH2, CF3CH═CHF, and mixtures thereof; and relates to processes for making at least one hydrochlorotrifluoropropene product selected from the group consisting of CF3CCl═CH2, CF3CH═CHCl, and mixtures thereof.
