The object is to provide a process whereby it is possible to produce 2,3,3,3-tetrafluoropropene at a high conversion ratio constantly for a long period of time.
A process for producing 2,3,3,3-tetrafluoropropene, which comprises reacting a raw material compound of at least one of 1,1-dichloro-2,3,3,3-tetrafluoropropene and 1-chloro-2,3,3,3-tetrafluoropropene, and hydrogen, in the presence of a catalyst, wherein the catalyst is a noble metal catalyst supported on a metal oxide having a Hammett acidity function value (H
0
) of at least −5.6.
该过程的目的是提供一种方法,可以在长时间内以高转化率持续生产2,3,3,3-四氟丙烯。
一种生产2,3,3,3-四氟丙烯的方法,包括在催化剂存在下,将至少一种1,1-二氯-2,3,3,3-四氟丙烯和1-氯-2,3,3,3-四氟丙烯的原料化合物与氢反应,其中催化剂是贵金属催化剂,支撑在具有至少-5.6的Hammett酸度函数值(H0)的金属氧化物上。
