“…Additionally, it is reported that an azeotropic mixture of cyc-CF 2 CF 2 CF 2 CHFCH 2 with C 3 H 7 Br, trans -CHClCHCl, and CH 2 Cl 2 can be used in various applications such as foam-blowing agent, solvent in refrigeration flushing, oxygen system cleaning, paints, adhesives and lubricants, etc . An analogous compound, trans -cyc-CF 2 CF 2 CF 2 CHFCHF ( trans -1,1,2,2,3,3,4,5-octafluorocyclopentane), has also been considered as solvent . Similarly, cyc-CF 2 CF 2 CF 2 CHCH– has been developed as a useful detergent. , The attractive properties of HFOs give us hope of their worth consideration for improvement in the environmental performances of air conditioning, refrigeration systems, and other applications.…”
