Compositions comprising multi-fluorinated olefins and HFC-32 are disclosed. Such compositions are useful particularly for in stationary refrigeration and air conditioning equipment.

Compositions containing difluoromethane and fluorine substituted olefins

Various compositions, including particularly aerosol compositions, containing fluorinated olefins, including particularly tetra- and penta-fluorpropenes, in a variety of applications are disclosed.

Heat transfer compositions, methods and systems

A process for the manufacture of haloalkanes, or more particularly to a process for the manufacture of 1,1,1,3,3-pentachloropropane (HCC-240fa) and/or 1,1,1,3-tetrachloropropane (HCC-250fb). The process includes (a) mixing a catalyst, co-catalyst and a haloalkane starting material under conditions suitable to produce a homogeneous mixture; (b) reacting the homogeneous mixture with a haloalkene and/or alkene starting material under conditions suitable to produce a haloalkane product stream; and (c) recovering a haloalkane product from said product stream.

Process for the manufacture of 1,1,1,3,3-pentachloropropane

Heat transfer methods

The present invention discloses a manufacturing process to produce high purity 1234yf from 245eb, which preferably includes the removal of impurities present in 245eb raw material, the dehydrofluorination of 245eb, and the removal of impurities present in final crude product. The disclosed manufacturing process allows the production of a 1234yf product with lower the levels of 1225ye and/or trifluoropropene, preferably in amounts of less than about 500, and 50 ppm, respectively.

Process for producing 2,3,3,3-tetrafluoropropene

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.

Compositions containing chlorofluoroolefins or fluoroolefins

The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms.

[object Object]

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 (CO) and from about 99 to about 60 percent, on a weight basis, of a compound having the Formula I XCFR(I), where X is a Cor a Cunsaturated, 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.

Compositions containing tetrafluoropropene and carbon dioxide

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.
