AZEOTROPE-LIKE COMPOSITIONS OF 1,1-DICHLORO-1-FLUOROETHANE, DICHLOROTRIFLUOROETHANE, AND NITROMETHANE

摘要

Azeotrope-like compositions comprising 1,1-dichloro-1-fluoroethane, dichlorotrifluoroethane, and nitromethane are stable and have utility as solvents in a variety of industrial cleaning applications including cold cleaning and defluxing of printed circuit boards. The azeotrope-like compositions may also comprise effective stabilizing amounts of phosphite ester and one of tertiary alcohol and 1,2-epoxyalkane having 2 to 7 carbon atoms.
