The object is to provide a process for producing highly pure 2,3,3,3-tetrafluoropropene, whereby formation of 3,3,3-trifluoropropene is suppressed.
A process for producing 2,3,3,3-tetrafluoropropene, which comprises reacting a raw material compound composed of 1,1-dichloro-2,3,3,3-tetrafluoropropene and/or 1-chloro-2,3,3,3-tetrafluoropropene, and hydrogen in a gas phase in a reactor having a catalyst layer packed with a catalyst-supporting carrier, while maintaining the maximum temperature of the catalyst layer to be at most 130° C., to obtain formed gas containing 2,3,3,3-tetrafluoropropene, and then, contacting the formed gas discharged from the reactor, with alkali at a temperature of at most 100° C.
该方法旨在提供生产高纯度2,3,3,3-四氟丙烯的过程,通过抑制3,3,3-三氟丙烯的生成。
一种生产2,3,3,3-四氟丙烯的方法,包括在具有填充有催化剂支撑载体的催化剂层的反应器中,在气相中将由1,1-二氯-2,3,3,3-四氟丙烯和/或1-氯-2,3,3,3-四氟丙烯组成的原料化合物与氢反应,同时保持催化剂层的最高温度不超过130°C,以获得含有2,3,3,3-四氟丙烯的生成气体,然后将从反应器排放的生成气体与碱在不超过100°C的温度下接触。
