A process for transferring heat including providing an article and contacting the article with a heat transfer media. The heat transfer media includes a composition formed by the process of, contacting a compound of formula (1), RfCH=CHF, with a fluorinated ethylene compound of formula (2), CX1X2=CX3X4 in the presence of a Lewis acid catalyst. In the compound of formula (1) Rf is a C1-C10 perfluorinated alkyl group. In the compound of formula (2) X1, X2, X3, and X4 are each independently H, Cl, or F and at least one of X1, X2, X3, and X4 is F. The resulting composition comprises a compound of formula (3), RfCF3(CX5X6CX7X8)nCH=CHCX9X10CX11X12F. In the compound of formula (3), X5, X6, X7, X8, X9, X10, X11, and X12 are each independently H, Cl, or F, and n is an integer of 0 or 1.
一种传热的方法,包括提供一种物品并将该物品与传热介质接触。该传热介质包括在路易斯酸催化剂的存在下,将式(1)化合物RfCH=CHF与式(2)氟化乙烯化合物CX1X2=CX3X4接触形成的组合物。在式(1)化合物中,Rf是C1-C10全氟烷基。在式(2)化合物中,X1、X2、X3和X4各自独立地表示H、Cl或F,并且X1、X2、X3和X4中至少有一个是F。所得到的组合物包括式(3)化合物RfCF3(CX5X6CX7X8)nCH=CHCX9X10CX11X12F。在式(3)化合物中,X5、X6、X7、X8、X9、X10、X11和X12各自独立地表示H、Cl或F,n是0或1的整数。
