PURPOSE:To obtain the subject novel mixture, consisting of trichlorotrifluoroethane and a binary azeotropic mixture of methanol- dichloroethylene, usable as a substitute fluorocarbon and simultaneously having excellent characteristics as a solvent, etc. CONSTITUTION:The objective mixture consisting of (A) 95-20wt.% (optimally about 50wt.%) 1,1,2-trichlorotrifluoroethane and (B) 5-80wt.% (optimally about 50wt.%) binary azeotropic mixture of methanol and cis-1,2-dichloroethylene. The above-mentioned mixture is used as a remover for fluxes, greases, oils, waxes, inks, etc., solvent for coatings, extracting agent, stain removing agent, detergent for IC parts, electrical appliances, precise machines, optical lenses, etc., and draining agent, etc. |
