Regioselective nitration of aromatic compounds and the reaction products thereof |
| abstract |
A method is described for the regioselective nitration of substituted aromatic compounds. The reaction is effected by heating the aromatic compound to a temperature within the range of 70-90° C. in the presence of a solid zeolite catalyst and adding concentrated nitric acid to the heated mixture, the concentration of the acid ranging from 90-98%, by weight. |
