| Abstract: | The nitration of 1,2,3-trichlorobenzene were explored in the nitration system of nitric acid/sulfuric acid,potassium nitrate/sulfuric acid and organic solvent.The effects of molar ratio of raw materials,reaction temperature and reaction time on the 4,6-dinitro-1,2,3-trichlorobenzene yield were evaluated in the system of nitric acid/sulfuric acid.The optimum conditions were selected in the system of 65% nitric acid/98% sulfuric acid as follows:molar ratio of 1,2,3-trichlorobenzene to sulfuric acid to nitric ... |
