Reaction Conditions:
with sulfolane;sodium hydrogencarbonate at 210; for 2 h;
Steps:
10 Preparation of 2,6-dimethylnitrobenzene
2.0 kg of sulfolane was added to the reaction vessel, and 195 g (1 mol) of 2,4-dimethyl-3-nitrobenzoic acid and 168 g (2 mol) of sodium hydrogencarbonate were successively added, and the reaction vessel was heated to 210 ° C and kept for 2 h. After completion of the reaction, the temperature of the reaction vessel was lowered to about 130 ° C, and the solvent was distilled off under reduced pressure, followed by distillation to give the title compound 143.4 g, yield 95%.
