Azeotrope-Like Composition Containing Fluorinated Olefin as Component
What is disclosed is a liquid composition containing: 80 mol % to 99.9999 mol % of (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 0.0001 mol % to 20 mol % of (E)-1,2-dichloro-3,3,3-trifluoropropene (1223E). The liquid composition has small impact on the global environment and exerts azeotrope-like properties. Therefore, the composition of the liquid composition is not substantially changed even when the liquid composition is used in an open system or used for a long period. The composition of the liquid composition is also rarely changed even when the liquid composition is recovered by distillation. Therefore, the liquid mixture according to the present invention can be used suitably as a cleaning agent (a solvent).
Compositions containing chlorofluoroolefins or fluoroolefins
Compositions and methods based on the use of fluoroalkene containing from 3 to 4 carbon atoms and at least one carbon-carbon double bond, such as HFO-1214, HFO-HF0-1233, or HF0-1354 having properties highly beneficial in foaming and blowing agent applications, articles and methods.
SOLVENT COMPOSITION, CLEANING METHOD AND METHOD OF FORMING A COATING FILM
There is provided a solvent composition which is a stable solvent composition which is excellent in solubility of various organic substances, has a sufficient drying property, and has no adverse effect on a global environment, is stabilized not to decompose, and moreover suppresses metal corrosion under coexistence with metal, and which can be used without having an adverse effect on articles of various materials such as metal, plastic, and elastomer in a wide range of industrial uses such as cleaning and dilution coating uses. A solvent composition including: a solvent (A) including (Z)-1-chloro-3,3,3-trifluoro-1-propene; and a stabilizer (B) consisting of HCFC whose boiling point at normal pressure is not lower than 30 C. nor higher than 60 C.
AZEOTROPIC AND AZEOTROPE-LIKE COMPOSITIONS OF Z-1-CHLORO-3,3,3-TRIFLUOROPROPENE
This application provides azeotropic and near-azeotropic compositions of Z-1233zd and a second component selected from the group consisting of Z-1336mzz, Isopentane, E-1438ezy, E-1233zd and HBFO-1233xfB. The inventive compositions are useful as aerosol propellants, refrigerants, cleaning agents, expansion agents for thermoplastic and thermoset foams, solvents, heat transfer media, gaseous dielectrics, fire extinguishing and suppression agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents. The compositions were modeled based on Vapor-Liquid Equilibria data such as those of the Z-1233zd/Isopentane system shown in FIG. 3.
