Claims57
A composition, comprising:
- i) 1,2-dichloro-1,2-difluoroethylene;
- and
- ii) a compound selected from R-245fa, n-pentane, R-1233zdE, i-pentane, R-1336mzzE, R-1224ydZ, R-1234zeZ, R-1336yf, and R-1336zeE, wherein when the compound is R-245fa, the 1,2-dichloro-1,2-difluoroethylene is present in the composition at a concentration of about 1 to about 40 weight percent and R-245fa is present in the composition at a concentration of about 99 to about 60 weight percent R-245fa.
