| Abstract: | 2 - Nitro - m - xylene and 4 - nitro - m - xylene were prepared form m - xylene by subsection nitrotion. The yield of the mixture of 2 - nitro - m - xylene and 4 - nitro - m - xylene was 94%. The right conditions were founded form m - xylene to 2 - nitro - m - xylene and 4 - nitro - m - xylene. The time of the nitrotion and reaction temperature and mixed acid on the yield were discussed by experiment. |
