  • Publication number: 20170239638
    Abstract: The invention relates to a process to prepare tetrahalopropenes, such as 2-chloro-3,3,3-trifluoropropene (1233xf). The process comprises atomizing a feed material, such as 1,2,3-tetrachloropropene (1230xa) and the like, and mixing it with superheated HF to form a vaporized composition of feed material and HF with substantially instantaneous contact with a vapor phase fluorination catalyst. The invention extends catalyst life and forestalls catalyst deactivation.

  • Publication number: 20170158585
    Abstract: The invention provides an improved process to manufacture 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) by reacting 2-chloro-3,3,3,-trifluoropropene (HCFO-1233x1) with hydrogen fluoride, in a liquid phase reaction in the presence of hydrogen chloride and a liquid phase fluorination catalyst. The hydrogen chloride is added into the reaction from an external source at a pressure of about 100 psig or more. The HCFC-244bb is an intermediate in the production of 2,3,3,3-tetrafluoropropene-1 (HFO-1234yf).

  • Patent number: 9670117
    Abstract: The present invention relates, in part, to the discovery that, during the fluorination of certain fluoroolefin starting reagents, particularly, 1,1,2,3-tetrachloropropene (1230xa), oligomerization/polymerization of such starting reagents reduces the conversion process and leads to increased catalyst deactivation. The present invention also illustrates that providing one or more organic co-feed to the fluoroolefin starting stream reduces such oligomerization/polymerization and improves catalystic stability.

  • Patent number: 9650320
    Abstract: Disclosed are processes for a high temperature isomerization reaction converting (E)-1-chloro-3,3,3-trifluoropropene to (Z)-1-chloro-3,3,3-trifluoropropene. In certain aspects of the invention, such a process includes contacting a feed stream with a heated surface, where the feed stream includes (E)-1-chloro-3,3,3-trifluoropropene or mixture of (E)-1-chloro-3,3,3-trifluoropropene with (Z)-1-chloro-3,3,3-trifluoropropene. The resulting product stream includes (Z)-1-chloro-3,3,3-trifluoropropene and (E)-1-chloro-3,3,3-trifluoropropene, where the ratio of (Z) isomer to (E) isomer in the product stream is higher than the ratio feed stream. The (E) and (Z) isomers in the product stream may be separated from one another.

  • Patent number: 9643903
    Abstract: Disclosed is process for the production of (E) 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) by conducting a continuous reaction without the use of a catalyst. Also disclosed is an integrated system for producing hydrofluoro olefins, particularly 1233zd(E). The manufacturing process includes six major unit operations: (1) a fluorination reaction of HCC-240fa (in continuous or semi-batch mode) using HF with simultaneous removal of by-product HCl and the product 1233zd(E); (2) recycle of unreacted HCC-240fa and HF together with under-fluorinated by-products back to (1); (3) separation and purification of by-product HCl; (4) separation of excess HF back to (1); (5) purification of final product, 1233zd(E); and (6) isomerization of by-product 1233zd(Z) to 1233zd(E) to maximize the process yield.

  • Patent number: 9416074
    Abstract: The present invention relates, in part, to the discovery that the presence of impurities in a reactor for dehydrochlorinating HCFC-244bb to HFO-1234yf results in a reduced conversion rate and/or a selectivity changeover from HFO-1234yf to HCFO-1233xf. By substantially removing such impurities, it is shown that the conversion rate may be improved and selectivity to HFO-1234yf via dehydrochlorination of HCFC-244bb is also improved.
