摘要:
The invention relates to a process for manufacturing 1,1,1,2-tetrafluoropropene (1234yf, CF3—CF═CH2) from 1,1,3,3-tetrachlororopropene (1230za, CCl2═CH—CHCl2) and/or 1,1,1,3,3-pentachloropropane (240fa, CCl3CH2CHCl2). The process comprises an isomerization step of 1-chloro-3,3,3 trifluoropropene (1233zd, CF3—CH═CHCl) to 2-chloro-3,3,3 trifluoropropene (1233xf or CF3—CCl═CH2).
