摘要： This disclosure relates to processes which involve: contacting a mixture comprising at least one fluoroolefin and at least one alkyne impurity with at least one zeolite to reduce the concentration of the at least one alkyne 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.

摘要翻译： 本公开涉及涉及使包含至少一种氟烯烃和至少一种炔杂质的混合物与至少一种沸石接触以减少混合物中至少一种炔杂质的浓度的方法; 其中Rf是直链全氟烷基，X是H，F，Cl，Br或I; 并且所述至少一种沸石选自开孔度为至少4埃且不大于约5埃的沸石，孔开孔至少约5埃的沸石和不超过约2.6的孔氏体电离性， 及其混合物; 条件是至少一种沸石不是沸石4A。 本公开还涉及制备至少一种选自CF 3 CF = CH 2，CF 3 CH = CHF及其混合物的氢四氟丙烯产物的方法; 并且涉及制备选自CF 3 CCl = CH 2，CF 3 CH = CHCl的至少一种氯三氟甲苯产物及其混合物的方法。
