Abstract
Describes nonflammable organic solvent compositions comprising 1,2-dichloroethylene and a halocarbon different than 1,2-dichloroethylene. The 1,2-dichloroethylene consists essentially of trans-1,2-dichloroethylene, cis-1,2-dichloroethylene and mixtures thereof; preferably a major amount of trans-1,2-dichloroethylene; and in particular at least 99% by weight of trans-1,2-dichloroethylene, based on the total weight of 1,2-dichloroethylene. The halocarbon is selected from the group consisting of 1,1,1,3,3,3-hexafluoroisopropanol, perfluoro-tert-butyl alcohol, 1,1,2,3,3-pentafluoropropane, 1-bromo-2-chloro-1,1,2-trifluoroethane, 1,2-dichloro-1,1,2,3,3,3-hexafluoropropane and mixtures thereof.
