Abstract
Disclosed herein are multi-component, azeotrope-like compositions containing trans-dichloroethylene, 1,1,1,3,3-pentafluorobutane, and 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether. These compositions also form an azeotrope-like mixture with methanol. These compositions are useful as solvents in refrigeration flushing, oxygen system cleaning, foam blowing, and cleaning operations such as cold cleaning, vapor degreasing, and aerosol cleaners.
