ABSTRACT:
Nitrobenzenes are prepared by nitrating benzenes in vapor phase using nitric acid as a nitrating agent and under continuous or intermittent feeding of sulfuric acid as a catalyst in the presence of a catalyst comprising sulfuric acid supported on a carrier or in the presence of only a carrier. This process can provide very high and prolonged nitration activity.
