| Abstract: | Sulfur - catalyzed reduction of m - dinitrobenzene （ m - DNB ） to m - nitroaniline （ m - NA ） by CO/H20 with NaOH as a co - catalyst was studied. The effects of reacction conditions such as reaction temperature, reaction time, initial pressure of carbon monoxide, and the amount of sulfur, NaOH, water and solvent on the m -DNB conversion, m -NA selectivity and m -NA yield were investigated. The results showed that when the reaction was carried out under the following reaction conditios： reaction temperature 180 ℃, initial pressure of CO 6 MPa, reation time 4 hours, the amount of m - DNB, sulfur, NaOH, and water 2.5 mmol,0.02 g, 0.05 g and 2 mL respectively using THF as solvent, m -NA selectivity could reach 100% and both of m - DNB conversion and m - NA selectivity reached 93.97%. |
