    摘要: Disclosed are compositions useful in a wide variety of applications, including heat transfer fluids which possess a highly desirable and unexpectedly superior combination of properties, and heat transfer systems and methods based on these fluids. The preferred heat transfer fluid comprises from about 1 to about 40 percent, on a weight basis, of carbon dioxide (CO2) and from about 99 to about 60 percent, on a weight basis, of a compound having the Formula I XCFzR3-z (I), where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical, each R is independently Cl, F, Br, I or H, and z is 1 to 3. A preferred compound of Formula I is tetrafluoropropene, particularly 1,1,1,3-tetrafluoropropene and/or 1,1,1,3-tetrafluoropropene.

    摘要: The present invention discloses high purity E-1-chloro-3,3,3-trifluoropropene (1233zd(E)) and methods to produce the same. More specifically, the present invention discloses the methods of making 1233zd(E) essentially free of toxic impurities (e.g. 2-chloro-3,3,3-trifluoropropene (1233xf), chlorotetrafluoro-propene (1224), and 3,3,3-trifluoropropyne). The present invention further provides methods for making high purity 1233zd(E) with concentration of 1233xf and 1224 at or below 200 parts per million (ppm) and 3,3,3-trifluoropropyne impurities at or below 20 ppm. Formation of 1233xf impurity can be avoided if pure 1,1,1,3,3-pentachloropropane is used as a starting material. It was also found that formation of 1233xf is avoided if a liquid phase manufacturing process is used.

    摘要: A method for restraining a chemical discharge comprising (a) deploying a binding agent into a receptacle containing a hazardous material in a liquid state upon the occurrence of at least one predetermined event that increases the risk of accidentally discharging or leaking the hazardous material from the receptacle; and (b) contacting the hazardous material with the binding agent to form a composition comprising at least a portion of the hazardous material and the binding agent and having at least one property selected from a solid or semisolid state, a viscosity greater than the viscosity of the hazardous material at ambient conditions, a vapor pressure lower than the vapor pressure of the hazardous material at ambient conditions, and a surface tension greater that the surface tension of the hazardous material.
