摘要: A process for the manufacture of 1-chloro-3,3,3-trifluoropropene (HCFC-1233zd) at commercial scale from the reaction of HCC-240 and HF is disclosed. In one embodiment, HCC-240fa and HF are fed to a reactor operating at high pressure. Several different reactor designs useful in this process include; a stirred-tank reactor (batch and/or continuous flow); a plug flow reactor, a static mixer used as a reactor, at least one of the above reactors operating at high pressure; optionally combined with a distillation column running at a lower pressure; and combinations of the above; and/or with a distillation column. The resulting product stream consisting of 1233zd, HCl, HF, and other byproducts is partially condensed to recover HF by phase separation. The recovered HF phase is recycled to the reactor. The HCl is scrubbed from the vapor stream and recovered as an aqueous solution. The remaining organic components including the desired HCFC-1233zd are scrubbed, dried and distilled to meet commercial product specifications.

摘要: The present invention relates to polyurethane foams having a polymeric foam structure including a plurality of closed cells therein; and an HFO or HCFO blowing agent, including HCFO-1233zd or HFO-1234ze. In certain aspects, the present invention relates to foam premixes, and the resulting foam structures, that include HCFO-1233zd as blowing agent used alone, or in certain aspects, in a blend with a second co-blowing agent such as, but not limited to, cyclopentane, iso-pentane, or n-pentane.

摘要: The invention relates to a process for reducing the concentration of a fluorinated alkyne impurity, such as 3,3,3-trifluoropropyne (TFPY), in 2,3,3,3-tetrafluoropropene (HFO-1234yf) which comprises contacting such a mixture with a caustic material, such as sodium hydroxide (NaOH), under conditions effective to reduce the concentration of the fluorinated alkyne impurity, including in some practices reducing the concentration by at least 50%.

摘要: The current invention relates to a process for making a tetrafluoropropene using a tetrafluorochloropropane and/or a pentafluoropropane as starting or intermediate reagents. More specifically, though not exclusively, the present invention relates to a novel method for preparing a tetrafluoropropene by dehydrohalogenating a starting or intermediate tetrafluorochloropropane and/or pentafluoropropane material in the presence of a caustic solution at a temperature range greater than 40°C and less than or equal to 80°C.
