2,3,5,6-Tetrafluorobenzenamine Use and Manufacturing
2 Add 867.6 g of sulfuric acid with a mass fraction of 90percent to the reactor, raise the temperature to 100°C, and add 482 g of 4-amino-2, 3, 5, 6-tetrafluoroaniline at a uniform rate.4-amino-2, 3, 5, 6-tetrafluoroaniline was added within 2 hours. After the addition, the reaction was maintained at 100°C for 3 hours.165 g of water was added, and the concentration of sulfuric acid in the obtained solution was diluted to 80percent, and the temperature was raised to 120°C. The reaction was carried out for 10 hours, and the temperature was further raised to 130°C for 5 hours.Decrease to room temperature, under cooling conditions (The purpose of cooling is to ensure that the reaction system is in the roomTemperature), adding water 300g, dropping 45percent of sodium hydroxide aqueous solution 1715g neutralized to PH = 9, warming steam distillation, to obtain white solid product 2, 3, 5, 6-tetrafluoroaniline 410g, content of 99.8percent, Yield 98percent.Aniline 7 (15 g, 64 mmol) in concentrated H
