Also, the shape selectivity feature can be introduced favouring the formation of para-nitrotoluene, which is the most desired of the three isomers.
morphology of toluene-nitric acid dispersion, speed of agitation, temperature, catalyst/toluene and toluene/nitric acid ratios, dosing rate of reactants, boil-up rate (BR), and micro reaction environment and its influence on lattice aluminum transformation in catalyst are studied to achieve significant selectivity and yield enhancement of para-nitrotoluene.
