実験手順: A nitrogen-flushed, 500 ml 3-neck pot, equipped as described in Example 17, was charged with 340.3 g (1.56 mol) of ethyl-2-ethoxytetrafluoropropionate and 19.5 g (0.09 mol) of SbF5. Gas was evolved. The mixture was heated and distilled to give 220 g (83.0% yield) of ethyl trifluoropyruvate, b.p. 88° to 89°. The gaseous product was collected and identified by IR as largely ethyl fluoride. A nitrogen-flushed 500 ml 3-neck pot, equipped The mixture was heated distilled
