YieldReaction ConditionsOperation in experiment
[Example 1]; In a conical flask, 20.6 g of 95% sulfuric acid was slowly added dropwise to 70 g (2.2 mol) of methanol with ice cooling. Then, into a 300-ml glass autoclave, the resulting sulfuric acid/methanol solution and a 5% Rh/C catalyst (available from NE Chemcat Corporation, hydrous product) in an amount of 0.25 g on a dry weight basis were charged. The system was purged with hydrogen to make a hydrogen pressure 0.1 MPa at room temperature. Heating of the autoclave and stirring of the contents in the EPO <DP n="20"/>autoclave were started, and the temperature was increased to 400C and was held constant for 1 hour. After the autoclave was cooled, 10 g (50 mmol) of tetrafluoroterephthalonitrile (available from Tokyo Kasei Kogyo Co., Ltd.) was fed to the autoclave, and the temperature was raised to 700C in a nitrogen atmosphere. At 700C, introduction of hydrogen was started. The reaction pressure was controlled so that the hydrogen absorption rate should become not more than 10 ml/min. After a lapse of 6 hours and 30 minutes, absorption of hydrogen ceased. The quantity of hydrogen absorbed was 119% of the theoretical quantity of hydrogen absorbed. The reaction solution was filtered to separate the catalyst, and methanol was distilled off at atmospheric pressure. Thereafter, 100 g of water was added to the residue, and the mixture was refluxed by heating at an internal temperature of 1000C for 60 minutes. Then, methanol formed by hydrolysis of acetal was distilled off at atmospheric pressure. When the top temperature of the distillation reached 99C, the distillation was finished, and the resulting solution was cooled to room temperature. Then, the solution was extracted 3 times each with 30 g of toluene . EPO <DP n="21"/>From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis.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. [Example 2]The same operations as in Example 1 were carried out, except that as a catalyst a 5% Pd/C catalyst (available from NE Chemcat Corporation, hydrous product) was charged in an amount of 0.25 g on a dry weight basis. After a lapse of 3.3 hours, absorption of hydrogen ceased. The quantity of hydrogen absorbed was 117% of the theoretical quantity of hydrogen absorbed. Treatment of the reaction solution was carried out in the same manner as in Example 1.From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis. As a EPO <DP n="22"/>result of the analysis, a peak of the tetrafluoroterephthalonitrile as a raw material was below the detection limit, and the amount of tetrafluoroterephthalaldehyde was 68.9 mol%. On the other hand, the aqueous phase was neutralized and then subjected to GC analysis. As a result of the analysis, presence of14.8 mo1% of 2, 3, 5, 6-tetrafluorobenzylamine was confirmed.The results are set forth in Table 1.

Treatment of the reaction solution was carried out in the same manner as in Example 1.From the toluene extract, a small amount of a sample was withdrawn, and it was subjected to GC analysis.

[Example 7]; The same operations as in Example 1 were carried out, except that the catalyst used was changed from the 5% Rh/C catalyst (available from NE Chemcat Corporation, hydrous product) to a 2% Rh/C catalyst (available from NE Chemcat EPO <DP n="26"/>Corporation, hydrous product) . After a lapse of 7.3 hours, absorption of hydrogen ceased. The quantity of hydrogen absorbed was 114% of the theoretical quantity of hydrogen absorbed. Treatment of the reaction solution was carried out in the same manner as in Example 1.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 88.6 mol%, the amount of 2, 3, 5, 6-tetrafluorobenzene was 1.15 mol%, and the amount of 2, 3, 5, 6-tetrafluorobenzonitrile was 2.63 ralphaol%.

The results are set forth in Table 1.
