    • A process for the synthesis of hydrocchlorofluoro olefins (HCFO) and/or hydrofluoroolefins (HFO). The process is based on the steps of fluorination of hydrochloropropenes or hydrochloropropanes to form hydrochlorofluoropropenes and/or hydrofluoropropenes, followed by gas phase, catalytic fluorination of the hydrochlorofluoropropenes to form hydrofluoropropenes. The process produces 1,1, 1,2- tetrafluoropropene (HFO-1234yf) from "feedstock" such as tetrachloropropenes, 1,1,2,3 tetrachloropropene (HCO-1230xa) and/or 1,1,1,2 tetrachloropropene (HCO-1230xf) or pentachloropropanes, HCC-240db, HCC-240aa and/or HCC-240ab which are precursors of the tetrachloropropenes. The process of the present invention comprises the steps of: a) liquid phase or gas phase fluorination of tetrachloropropene (which may be formed via gas phase fluorination of pentachloropropane), in the presence or absence of homogenous or heterogeneous catalyst; to form the intermediate product HCFO- 1233xf and thereafter b) gas phase, catalytic fluorination of the intermediate HCFO-1233xf to form the hydrofluoropropene product 1,1,1,2-tetrafluoropropene (HFO-1234yf).
    • 一种合成氢氟氯氟烯烃(HCFO)和/或氢氟烯烃(HFO)的方法。 该方法基于氢氯丙烯或氢氯丙烷氟化以形成氢氯氟丙烯和/或氢氟丙烯的步骤,然后进行气相,氢氯氟丙烯的催化氟化以形成氢氟丙烯。 该方法从“原料”产生1,1,1,2-四氟丙烯(HFO-1234yf),例如四氯丙烯,1,1,2,3四氯丙烯(HCO-1230xa)和/或1,1,1,2-四氯丙烯( HCO-1230xf)或五氯丙烷,HCC-240db,HCC-240aa和/或HCC-240ab,它们是四氯丙烯的前体。 本发明的方法包括以下步骤:a)在存在或不存在均相或多相催化剂的情况下,四氯丙烯(其可通过五氯丙烷的气相氟化形成)进行液相或气相氟化; 形成中间产物HCFO-1233xf,然后b)中间体HCFO-1233xf的气相,催化氟化以形成氢氟丙烯产物1,1,1,2-四氟丙烯(HFO-1234yf)。

    • The present invention relates to blowing agent compositions comprising at least one hydrochlorofluoroolefin (HCFO) used in the preparation of foamable thermoplastic compositions. The HCFOs of the present invention include, but are not limited to, 1-chloro-3, 3,3-trifluoropropene (HCFO-1233zd), particularly the trans- isomer, 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf), dichloro-fluorinated propenes, and mixtures thereof. The blowing agent compositions of the present invention are used with coblowing agents including carbon dioxide, atmospheric gases, hydrofluorocarbons (HFC), hydrofluoroolefins (HFO), alkanes, hydrofluoroethers (HFE), and mixtures thereof. Preferred HFCs used as coblowing agents in the present invention include, but are not limited too, 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), pentafluorethane (HFC-125), difluoromethane (HFC-32). The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.
