摘要： The present invention relates, in part, to the discovery that the presence of impurities in 1,1,2,3-tetrachloropropene (1230xa) results in catalyst instability during the fluorination of 1230xa to 2-chloro-3,3,3-trifluoropropene. By substantially removing the impurities, it is shown that the catalyst life is extended and results in improved operation efficiency of the fluorination reaction. Such steps similarly result in an overall improvement in the production of certain hydrofluoroolefins, particularly 2,3,3,3-tetrafluoropropene (1234yf).
摘要翻译：本发明部分涉及发现在1,1,2,3-四氯丙烯（1230xa）中杂质的存在导致在1230xa氟化为2-氯-3,3,3-三氟丙烯期间的催化剂不稳定性。通过基本上除去杂质，显示催化剂寿命延长并且导致改善氟化反应的操作效率。这些步骤类似地导致某些氢氟烯烃，特别是2,3,3,3-四氟丙烯（1234yf）的生产的总体改进。
