PURPOSE:To provide a mixing washing solvent having a deterging power for fat or oil as high as that of 1,1,1-trichloroethane, having a low ozone depletion potential (ODP), a low solvency for plastic and is substantially free of a flashing point. CONSTITUTION:1,1,1-trichloroethane is mixed with a petroleum distillate of a boiling range of 100-300 deg.C to form a mixture of a 1,1,1-trichloroethane content of 45-95wt.%. |
