Disclosed are compositions comprising a compound having the formula CF 3 (CF 2 ) x CF═CFCF(OR)(CF 2 ) y CF 3 , wherein R is CH 3 or C 2 H 5 or mixtures thereof, and wherein x and y are independently 0, 1, 2 or 3, and wherein x+y=1, 2 or 3. Also disclosed are unsaturated fluoroethers selected from the group consisting of CF 3 (CF 2 ) x CF═CFCF(OR)(CF 2 ) y CF 3 , CF 3 (CF 2 ) x C(OR)═CFCF 2 (CF 2 ) y CF 3 , CF 3 CF═CFCF(OR)(CF 2 ) x (CF 2 ) y CF 3 , CF 3 (CF 2 ) x CF═C(OR)CF 2 (CF 2 ) y CF 3 , and mixtures thereof, wherein R can be either CH 3 , C 2 H 5 or mixtures thereof, and wherein x and y are independently 0, 1, 2 or 3, and wherein x+y=0, 1, 2 or 3. Also disclosed herein are novel methods of using a composition comprising at least one of the compounds described above as novel solvents, carrier fluids, dewatering agents, degreasing solvents or defluxing solvents. |
