Abstract:
An azeotrope-like mixture consisting essentially of chlorotrifluoropropene and at least one component selected from the group consisting of a C1 - C3 alcohol, a C5 - C6 hydrocarbon, a halogenated hydrocarbon, methylal, methyl acetone, water, nitromethane, and combinations thereof.
Abstract:
The invention provides solvent and cleaning compositions comprising an ionic surfactant, which preferably has a fluorinated portion thereof, and a solvent selected from hydrofluoro- and/or hydrochlorofluoro-olefins. Additionally, the invention provides drying, dry cleaning, and soil repellency compositions containing a hydrofluoro- or hydrochlorofluoro-olefin and said surfactant. Additionally, the invention provides drying compositions containing a hydrofluoro-olefin or hydrochlorofluoro-olefin and an alcohol such as methanol, ethanol or isopropanol.
Abstract:
Disclosed are compositions and methods for cleaning contaminated articles based on the provision of a zeotropic composition comprising (a) at least one flammable solvent having a boiling point at a first pressure; (b) at least one first nonflammable solvent having a boiling point at said first pressure which is less than about said first pressure boiling point of said flammable solvent; and (c) at least one second nonflammable solvent having a boiling point at said first pressure which is greater than about the first pressure boiling point of said flammable solvent.
Abstract:
Disclosed are compositions and methods for extracting oils comprising contacting material containing the oil with a composition comprising 1-chloro-3,3,3-trifluoropropene in an amount sufficient to dissolve at least a portion of the oil, and separating the solvent/oil solution from the material.
