Abstract

The vapour phase transformation of o-toluidine isomerisation has been studied over modified V-MO catalyst at different process parameters. The objective of this work is to evaluate the catalytic performance of modified V-MO catalyst carried out by impregnation method with acidic metal salts of Boron and Phosphorus qualitatively and quantitatively also with Mg doped catalyst and compare with parent supported V-Mo catalyst as well as modified catalyst obtained by Mg doping. Catalytic properties (conversion, selectivity) and thermodynamic properties (The Arrhenius activation energy, enthalpy, entropy and Gibbs’s free energy) are compared at ambient pressure and at identical reaction parameters using down-flow fixed bed reactor. Catalysts are characterized by x-ray diffractometry for any new phase formation and were ascertained by JCPDS diffraction files. The role of new phase (s) formation in the title reaction is justified.
