Procedure
From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis.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 89.4 mol %, the amount of 2,3,5,6-tetrafluorobenzene was 1.31 mol %, and the amount of 2,3,5,6-tetrafluorobenzonitrile was 1.03 mol %. On the other hand, the aqueous phase was neutralized and then subjected to GC analysis. As a result of the analysis, presence of 2.35 mol % of 2,3,5,6-tetrafluorobenzylamine was confirmed. The results are set forth in Table 1.
