    • The present invention provides a simple and efficient process for producing 2,3,3,3-tetrafluoropropene(HFC-1234yf), the process being useful for industrial production. More specifically, the present invention relates to: a process for producing 2,3,3,3-tetrafluoropropene, comprising the steps of: (I) reacting a compound expressed by Formula (1): CF3CF2CH2X   (1) wherein X represents Cl, Br or I, with a base to produce a compound expressed by Formula (2): CF3CF═CHX   (2) wherein X is the same as above; and (II) reducing the compound expressed by Formula (2) with hydrogen in the presence of a catalyst to produce 2,3,3,3-tetrafluoropropene.
    • 本发明提供了用于生产2,3,3,3-四氟丙烯(HFC-1234yf)的简单有效的方法,该方法可用于工业生产。 更具体地说,本发明涉及:制备2,3,3,3-四氟丙烯的方法,包括以下步骤:(I)使由式(1)表示的化合物:CF 3 CF 2 CH 2 X(1)其中X表示Cl, Br或I与碱反应,生成由式(2)表示的化合物:CF 3CF≡CHX(2)其中X与上述相同; 和(II)在催化剂存在下用氢还原由式(2)表示的化合物,生成2,3,3,3-四氟丙烯。
