Abstract

The present disclosure relates to processes for reducing the concentration of RfC=CX impurities in fluoroolefins. The process involves: contacting a mixture comprising at least one fluoroolefin and at least one RfC=CX impurity with at least one amine to reduce the concentration of the at least one RfCºCX impurity in the mixture; wherein Rf is a perfluorinated alkyl group, and X is H, F, CI, Br or I . The present disclosure also relates to processes for making at least one hydrotetrafluoropropene product selected from the group consisting of CF3CF=CH2, CF3CH=CHF, or at least one hydrochlorotrifluoropropene product selected from the group consisting of CF3CC1=CH2, CF3CH=CH1, and mixtures thereof and reducing the concentration of CF3C=CH impurity generated during the processes
