反応手順
Similarly to Example 1, 250 g of m-nitrotoluene was oxidized in the presence of 150 g of acetic acid, 4.5 g of cobalt acetate tetrahydrate and 2 g of sodium bromide at a pressure of 25 bar, a temperature of 135°-145° C. and a gas exhaust rate of 3 1/min, within a period of 200 minutes. The reaction mixture, diluted with 400 g of 69% acetic acid, was cooled to 5° C. with stirring, filtered, twice washed with 125 g of 50% acetic acid at 5° C. and once with 150 g of water, the mother liquor (514.5 g) and the combined washing filtrates (441 g) being recovered separately. After drying, 230 g of m-nitrobenzoic acid was obtained.
