| abstract |
The present invention discloses a composition comprising at least one unsaturated fluoroalkyl perfluoroolefin ether having a chemical formula selected from the group consisting of CF3: CF3 (CF2)xCF=CFCF(OR)(CF2)yCF3, CF3(CF2)xC(OR)=CFCF2(CF2)yCF3, CF3CF=CFCF(OR)(CF2)x(CF2)yCF3,CF3(CF2)xCF= C(OR)CF2(CF2)yCF3 and mixtures thereof; wherein x and y are independently 0, 1, 2, 3 or 4, and wherein x + y = 0, 1, 2, 3 or 4; and wherein R is 2,2,3,3-tetrafluoro-1-propyl, 2,2,3,3,3-pentafluoro-1-propyl, 2,2,2-trifluoro-1-ethyl, 2, 2,3,3,4,4,5,5-octafluoro-1-pentyl or 1,1,1,3,3,3-hexafluoro-2-propyl. Also disclosed herein is a novel method of using a composition comprising at least one of the above compounds as a novel solvent, carrier fluid, dehydrating agent, deoiling solvent or desoldering solvent. |
