发明名称 PROCESS FOR THE REDUCTION OF RFCCX IMPURITIES IN FLUOROOLEFINS
摘要 <p>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 RfC≡CX impurity in the mixture; wherein Rf is a perfluorinated alkyl group, and X is H, F, Cl, 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, and mixtures thereof and reducing the concentration of CF3C═CH impurity generated during the process. The present disclosure also relates to processes for making at least one hydrochlorotrifluoropropene product selected from the group consisting of CF3CCl═CH2, CF3CH═CHCl, and mixtures thereof and reducing the concentration of CF3C≡CH impurity generated during the process.</p>
