Description

Noram's Benzene Nitration Technology is an Adiabatic Process for making Mononitrobenzene, which minimizes the formation of Nitrophenols and Dinitrobenzene By-Products. The Process uses a Mixed Acid having less than 3 wt-% Nitric Acid, 55 to 80 wt-% Sulfuric Acid, and Water. The initial temperature of the Mixed Acid is in the range of 60 to 96°C. The Nitration Reaction is complete in about 300 seconds and produces less than 1,200 ppm Nitrophenols and less than about 80 ppm Dinitrobenzene. The Reaction can be carried out in a Plug-Flow or a Stirred Pot Reactor, or a combination of such Reactors.
