Abstract:
This invention provides azeotrope-like compositions of 1,1,1,2-tetrafluoroethane, 1,1,1,3,3-pentafluoropropane-245fa and 2-methylbutane that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
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.
Abstract:
This invention provides azeotrope-like compositions of 1, 1, 1, 2-tetrafluoroethane, 1,1,1,3,3-pentafluoropropane-245fa and water that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
Abstract:
The present invention provides compositions comprising an HFC component and a non-HFC component consisting essentially of methanol, having boiling points that are unexpectedly low and relatively constant, and uses thereof.
Abstract:
Disclosed are azeotrope-like compositions comprising 1,1,1,3,3-pentafluoropropane and at least one C3 or C4 hydrocarbon, and optionally water, said compositions are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
Abstract:
The present invention relates, in part, to compositions including at least one hydrofluoro-olefin or hydrochlorofluoro-olefin solvent. Such compositions may optionally contain one or more alcohols or other co-solvent or agent and may be used to provide one or more cleaning applications.
Abstract:
The present invention provides compositions comprising ranges of an HFC component (a mixture of 1,1,1,3,3-pentafluorobutane and 1,1,1,3,3-pentafluoropropane) and trans-1,2-dichloroethylene having unexpectedly low and relatively constant boiling points and uses of said compositions.
Abstract:
Un método para la limpieza de precisión al poner en contacto un espacio estrecho de un sustrato con una composición que comprende trans-1-cloro-3,3,3-trifluoropropeno y a continuación eliminar la composición del sustrato, en el que el espacio estrecho tiene un diámetro máximo que es inferior a 0,2 mm y en el que dicha composición tiene una tensión superficial de no más de 16 dinas/cm y un valor de Kauri-Butanol de no menos de 25.
