The present disclosure provides a process for producing trifluoroiodomethane, the process comprising providing a reactant stream comprising hydrogen iodide and at least one trifluoroacetyl halide selected from the group consisting of trifluoroacetyl chloride, trifluoroacetyl fluoride, trifluoroacetyl bromide, and combinations thereof, reacting the reactant stream in the presence of a first catalyst at a first reaction temperature from about 25° C. to about 400° C. to produce an intermediate product stream comprising trifluoroacetyl iodide, and reacting the intermediate product stream in the presence of a second catalyst at a second reaction temperature from about 200° C. to about 600° C. to produce a final product stream comprising the trifluoroiodomethane.

Processes for producing trifluoroiodomethane and trifluoroacetyl iodide

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

Method for retrofitting an existing heat transfer system comprising adding to said existing system a refrigerant consisting essentially of: (i) from about 25% to about 45% by weight of 1,1,1,2-tetrafluoroethane (HFC-134a); (ii) from 25% to about 35% by weight of trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) and/or 2,3,3,3-tetrafluoropropene (HFO-1234yf); and (iii) from about 37% to about 46% by weight of a combination of difluoromethane (HFC-32) and pentafluoroethane (HFC-125), provided that the weight ratio of HFO-32:HFC-125 is from about 1.21:1 to about 0.8:1, wherein the refrigerant preferably is a non-flammable refrigerant having a GWP of 1350 or less.

Refrigerant compositions and use thereof in systems using flooded evaporators

The present disclosure provides minimum-boiling, homogeneous azeotropic and azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane ('TFMCB') with each of ethanol, n-pentane, cyclopentane, trans-1,2-dichloroethylene, and perfluoro(2-methyl-3-pentanone).

Azeotrope or azeotrope-like compositions of 1,2,2-trifluoro-1-trifluoromethylcyclobutane (TFMCB) and applications thereof

The present invention provides a refrigerant composition comprising: (a) from about 65% by weight to about 90% by weight of HFO-1234ze(E); (b) from about 10% by weight to about 35% by weight of HFO-1336mzz (E); and optionally (c) from about 0% to about 4.4% by weight of HFC-227ea for use in a variety of refrigeration applications, including air conditioning and/or refrigeration and particularly cooling products such as fruits, vegetables and beverages without exposing those articles to temperatures below the freezing point of water.

Nonflammable refrigerants having low GWP, and systems for and methods of providing refrigeration

The present disclosure provides azeotrope or azeotrope-like compositions including trifluoroiodomethane (CFI) and trifluoroacetyl chloride (CFCOCl), and a method of forming an azeotrope or azeotrope-like composition comprising the step of combining trifluoroacetyl chloride (CFCOCl) and trifluoroiodomethane (CFI) to form an azeotrope or azeotrope-like composition.
