Versuchsvorschrift

From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis.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, the tetrafluoroterephthalonitrile as a raw material remained in an amount of 21.0 mol %, and tetrafluoroterephthalaldehyde was obtained in an amount of only 5.0 mol %. The amount of 2,3,5,6-tetrafluorobenzene was 0.65 mol %, the amount of 2,3,5,6-tetrafluorobenzonitrile was 0.53 mol %, and 1-cyano-2,3,5,6-tetrafluorobenzaldehyde wherein a nitrile group on only one side had reacted was obtained in an amount of 63.1 mol %. On the other hand, the aqueous phase was neutralized and then subjected to GC analysis. As a result of the analysis, presence of 2.88 mol % of 2,3,5,6-tetrafluorobenzylamine was confirmed. The results are set forth in Table 2.
