Reaktionsschritte

From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis. As a result of the analysis, a peak of the tetrafluoroterephthalonitrile as a raw material was below the detection limit, the amount of tetrafluoroterephthalaldehyde was 92.0 mol %, the amount of 2,3,5,6-tetrafluorobenzene was 0.94 mol %, and the amount of 2,3,5,6-tetrafluorobenzonitrile was 0.79 mol %. On the other hand, the aqueous phase was neutralized and then subjected to GC analysis. As a result of the analysis, presence of 3.39 mol % of 2,3,5,6-tetrafluorobenzylamine was confirmed. The results are set forth in Table 1.
