Azeotropic nitration of benzene |
| abstract |
A process for the mononitration of benzene wherein the nitration is carried out at temperatures of at least 120*C. in mixed HNO3H2SO4 and excess water is carried overhead as an azeotrope with part of the benzene and is then decanted from the benzene. The heat of nitration can be used to vaporize the azeotrope. The nitrated benzene product is removed as bottoms and decanted from the acid phase. This avoids the necessity of reconcentratingn the H2SO4. |
