The present application provides binary azeotrope or azeotrope-like compositions comprising perfluoroheptene and an additional component, wherein the additional component is present in the composition in an amount effective to form an azeotrope composition or azeotrope-like composition with the perfluoroheptene. Methods of using the compositions provided herein in cleaning and carrier fluid applications are also provided.

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (“TFMCB”) with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

Disclosed herein are a solvent composition and methods of using the solvent composition. The solvent composition includes at least 80 wt. % of trans-1,2-dichloroetheylene (t-DCE), and 0.1 to 20 wt. % of at least one organic compound. The organic compound may be a hydrocarbon and/or an oxygenated solvent. The solvent composition may be used to clean a surface by contacting the surface with the composition to dissolve a contaminant on the surface. The composition may be used to remove a coating from a surface of a substrate by contacting the surface with the solvent composition to dissolve the coating and removing the composition containing the coating from the surface. The composition may also be used to deposit material on a substrate by dissolving the material in the solvent composition, applying the composition containing the material onto the substrate, and evaporating the composition from the substrate.

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.

The present application provides quaternary azeotrope or azeotrope-like compositions comprising trans-dichloroethylene and three or more additional components. Methods of using the compositions provided herein in cleaning, defluxing, deposition, and carrier fluid applications are also provided.

The present invention provides a composition, such as a refrigerant composition comprising 1, 1-difluoroethene (vinylidene fluoride, R-1132a); trifluoromethane (R-23); and one or more compound selected from hexafluoroethane (R-116), ethane (R-170) and carbon dioxide (R-744, CO.sub.2).

This application provides azeotropic and near-azeotropic compositions of Z-1,1,1,4,4,4-hexafluorobut-2-ene (Z-HFO-1336mzz) and a second component selected from the group consisting of n-butane and isobutane. The inventive compositions are useful as aerosol propellants, refrigerants, cleaning agents, expansion agents for thermoplastic and thermoset foams, solvents, heat transfer media, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.
