Abstract
The present invention provides compositions comprising an HFC component and a non-HFC component consisting essentially of methanol, having boiling points that are unexpectedly low and relatively constant, and uses thereof.
Claims20
A composition comprising:
- an HFC component consisting essentially of 1,1,1,3,3-pentafluorobutane and 1,1,1,3,3-pentafluoropropane;
- and
- from greater than 0 to about 23 weight percent of a non-KEG component consisting essentially of trans-1,2-dichloroethylene, said weight percent being based upon the total weight of the HFC component and the non-HFC component.
A composition comprising:
- an HFC component consisting essentially of 1,1,1,3,3-pentafluorobutane and 1,1,1,3,3-pentafluoropropane;
- and
- from greater than 0 to about 23 weight percent of the composition of a non-HFC component consisting essentially of trans-1,2-dichloroethylene.
