Japanese Patent JPH0233025
Kind Code:
B2
Abstract:
Nitrobenzene and other aromatic nitro compounds can be obtained efficiently by the mixed acid nitration process by passing nitrogen or other gas inert to the nitration reaction through the reaction mass during reaction. The inert gas captures water, introduced for example with reaction feedstuffs, and so enables the sulfuric acid concentration to be maintained in an optimum range from 70-75% by weight to ensure sufficient generation of nitronium ions to act as nitrating agent.
