Continuous adiabatic process for the mononitration of benzene |
摘要 |
Benzene is admixed and reacted continuously with a mixed acid containing 3-7.5% nitric acid, 58.5-66.5% sulfuric acid, and 28-37% water under pressure sufficient to maintain benzene in liquid state until complete conversion of nitric acid is achieved to provide mononitrobenzene containing less than 500 ppm dinitrobenzene.
