Abstract

Stabilized azeotrope-like compositions comprising 1,1-dichloro-1-fluoroethane, dichlorotrifluoroethane, nitromethane, and ethanol or methanol and effective amounts of 1,2-epoxyalkane having 3 to 7 carbon atoms have utility as degreasing agents and as solvents in a variety of industrial cleaning applications including cold cleaning, dry cleaning, and defluxing of printed circuit boards.
