Kinetics of Cyclization of propylene glycol and ethylene diamine to 2-methyl pyrazine has been studied over alumina-supported nanocrystalline MnFe2O4 catalyst in a differential flow fixed bed reactor in the temperature range 473 -573 K. The partial pressures of propylene glycol and ethylene diamine were varied and rates were measured for the formation of 2 Methyl Pyrazine. Product selectivity as well as rate of formation of 2-methyl pyrazine was influenced by partial pressure of reactants. The rate equation R = k KP.KE PP PE / (1+ K P PP+K E PE) 2 deduced, on the basis of adsorption of PG and ED in gas phase represented the data most satisfactorily.
