The present application provides compositions comprising 1,2-dichloro-1,2-difluoroethylene (i.e., CFO-1112) and, optionally, an additional component. The present application further provides use of the compositions provided herein in cleaning, solvent, carrier fluid, and deposition applications.

A liquid composition according to one embodiment of the present invention contains 0.0001 mol % to 40 mol % (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 99.9999 mol % to 60 mol % (E)-1,2-dichloro-ethylene (t-DCE). The liquid composition has less influence on the global environment and azeotropic (or azeotrope-like) properties. There occurs practically no composition change even when the liquid composition is used in an open system or used for a long term. Further, it is less likely that there will occur a composition change even when the liquid composition is recovered by distillation. The liquid composition is thus suitably usable as a cleaning agent (solvent). In particular, the liquid composition of 90 mol % or less of t-DCE is classified as non-hazardous under the Fire Serves Act.

Disclosed are azeotropic compositions comprising a perfluoroheptene, and a chlorotrifluoropropene. Also disclosed herein are novel methods of using these compositions as novel solvents, degreasing or defluxing solvent, or carrier fluids.

A cleaning solvent composition comprises from about 70 to about 95.7 weight percent trans-dichloroethylene, from about 15 to about 3.8 weight percent heptafluorocyclopentane, and from about 15 to about 0.5 weight percent of methylperfluoroheptene ethers. The composition may comprise from about 88 to about 94.2 weight percent trans-dichloroethylene, from about 6 to about 3.8 weight percent heptafluorocyclopentane, and from about 6 to about 2 weight percent of methylperfluoroheptene ethers. A method for cleaning articles of soiling substances comprises contacting the articles with the solvent composition by any suitable means such as a spray delivered by a propellant gas, or by contact with liquid and/or vapor solvent compositions, as in a conventional vapor degreaser apparatus.

There are provided a solvent composition containing tDCE, which does not exert an adverse effect on the global environment, has high solubility and incombustibility, and can maintain initial incombustibility even in use accompanied by a phase change, a cleaning method using the solvent composition, a coating film-forming composition including the solvent composition, and a method of forming a homogeneous coating film using the coating film-forming composition. A solvent composition includes: tDCE; a first HFE having a boiling point of 40 to 65 C.; and a second HFE having a boiling point of 70 to 120 C., in which a ratio of tDCE is 65 to 80 mass %, a ratio of the first HFE is 5 to 25 mass %, and a ratio of the second HFE is 5 to 25 mass % with respect to a total amount of tDCE, the first HFE, and the second HFE.
