3-nitrotoluene; m-nitrotoluene
Brief introduction: 3-nitrotoluene is obtained from toluene nitrated with mixed acid below 50℃, then fractionated and refined. With the different reaction conditions and catalysts, different products can be obtained, such as o-nitrotoluene, p-nitrotoluene, m-nitrotoluene, 2, 4-dinitrotoluene and 2, 4, 6-trinitrotoluene. Nitrotoluene and dinitrotoluene are important intermediates in medicine, dyes and pesticides. In the general reaction conditions, there are more ortho products than para-sites in the three intermediates of nitrotoluene, and para-sites are more than para-sites. At present, the domestic market has a great demand for adjacent and para-nitrotoluene, so the localization nitration of toluene is studied both at home and abroad, hoping to increase the yield of adjacent and para-toluene as much as possible. However, there is no ideal result at present, and the formation of a certain amount of m-nitrotoluene is inevitable. Because the development and utilization of p-nitrotoluene has not kept up in time, the by-product of nitrotoluene nitration can only be sold at a low price or a large amount of inventory is overstocked, resulting in a great consumption of chemical resources.
