Abstract: The present invention relates to solvent/cleaner and heat transfer fluid compositions comprising at least one hydrochlorofluoroolefin (HCFO), 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), particularly the trans-isomer. The HCFO of the present invention can be used in combination with co-agents including, hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs), hydrocarbons, ethers including hydrofluoroethers (HFEs), esters, ketones, alcohols, 1,2-transdichloroethylene and mixtures thereof.

Abstract: The present invention relates to formulated refrigerant systems of 1-chloro-3,3,3-trifluoropropene (R-1233zd) that are sufficiently thermally and chemically stable such that they can be effectively used sans additional stabilizers. The formulations of the present invention are particularly useful compositions for refrigeration, heat transfer and foam blowing.

Abstract: Hydrofluoroolefins and hydrochlorofluoroolefins contaminated with acid and/or iron compounds are purified and stabilized by contacting the haloolefin with a solid adsorbent such as alumina and then combining the purified haloolefin with one or more stabilizers such as an epoxide. The purified, stabilized haloolefins thus obtained are useful in a wide variety of end-use applications, including, for example, as refrigerants, propellants, foaming agents, fire suppression or extinguishing agents, and solvents.

Abstract: A blowing agent for thermosetting foams is disclosed. The blowing agent is a hydrofluoroolefin (HCFO), preferably HFCO-1234yf in combination with a hydrochlorofluoroolefin (HCFO) preferably one selected from HCFO-1233zd, HCFO-1223, HCFO-1233xf and mixtures thereof. The blowing agent is effective as a blowing agent in the manufacture of thermosetting foams.

Abstract: Disclosed are the combinations containing Z and E stereoisomers of hydrofluoroolefins where the more toxic isomer is less than about 30% weight of the combination (vs the sum of Z+E), to minimize the toxicity impact in the applications they will be used for such as cooling and heat fluids, foams blowing agents or solvents. Also disclosed are means to obtain combinations containing Z and E stereoisomers of hydrofluoroolefins.

Abstract: A method for producing a tetrafluoroolefin, such as 2,3,3,3-tetrafluoropropene (HFO-1234yf), comprises dehydrofluorinating a pentafluoroalkane in a gas phase in the presence of a catalyst comprising chromium oxyfluoride. In a preferred embodiment, 2,3,3,3-tetrafluoropropene (HFO-1234yf) is produced by forming a catalyst comprising chromium oxyfluoride by calcining CrF3.xH2O, where x is 1-10, in the presence of a flowing gas comprising nitrogen to form a calcined chromium oxyfluoride, and dehydrofluorinating 1,1,1,2,2-pentafluoropropane (HFC-245cb) in a gas phase in the presence of the catalyst to form the 2,3,3,3-tetrafluoropropene (HFO-1234yf).

Abstract: A method of separating a composition containing at least one organofluorine compound from at least one inorganic compound by contacts the composition with a semipermeable membrane. Other methods separate a organofluorine compound from a composition containing at least one other organofluorine compound or chlorocarbon. Methods also include isolating a single organofluorine compound from a composition comprising a mixture of organofluorine compounds, chlorocarbons, and/or inorganic compounds.

Abstract: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrofluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.
