Zusammenfassung:33The invention relates to a new industrial process for manufacturing of perfluoro(methylvinylether) (PFMVE), and of 1,1,2,2-tetrafluoro-1-(trifluoromethoxy)ethane (TFTFME) (E 227), involving reactions in liquid phase and performing reactions, for example, in a (closed) column reactor or in a microreactor, respectively. The invention also relates to a new industrial process for manufacturing of perfluoro(methyl vinyl ether) (PFMVE) by HF-elimination from the compound 1,1,2,2-tetrafluoro-1-(trifluoromethoxy)ethane (TFTFME) (E 227). The invention also relates to a new industrial process for manufacturing of the compound 1,1,2,2-tetrafluoro-1-(trifluoromethoxy)ethane (TFTFME) (E 227) by selective fluorination of the compound HFE-254 (1,1,2,2-tetrafluoro-1-(methoxy)ethane), i.e., perfluorination of only the CHO-group (i.e., methoxy-group) of the compound HFE-254 is selectively fluorinated to a CFO-group (i.e., trifluoromethoxy-group).
