Abstract

The mononitration of toluene by mixed acid has been taken as a specific case of a heterogeneous reaction, and a mathematical model has been developed that simultaneously takes into account mass transfer phenomena and chemical kinetics. Furthermore, the effect of phase inversion on the overall reaction rate has been included. An extensive experimental programme has been followed, using adiabatic and heat flow calorimetry, supported by chemical analysis. A series of toluene nitration experiments was carried out to study the influences of different operating conditions such as temperature, stirring speed, feeding rate and H(2)SO(4) concentration, and to compare these with the simulation predictions. The results and their implications for analysing and subsequently optimising these types of processes from the points of view of performance and safety are presented.
