Abstract
The present invention provides stabilized compositions comprising dichlorotrifluoroethane and effective stabilizing amounts of alkanol having 4 or 5 carbon atoms, nitroalkane having 1 to 3 carbon atoms, and a third component of 1,2-epoxyalkane having 2 to 7 carbon atoms or phosphite ester. Stabilized dichlorotrifluoroethane is useful in a variety of vapor degreasing, cold cleaning, and solvent cleaning applications including defluxing.
