The production of 1 methoxy 2 propanol by catalytic reaction in a rectification column was studied.The kinetics for 1 methoxy 2 propanol in the presence of the catalyst UL301 were determined experimentally in a batch reactor,with the property data estimated by Aspen Plus. The paper presents results of computer simulations of synthesis of 1 methoxy 2 propanol in a catalytic distil lation column,and gives optimum operating conditions.It discusses the catalytic capability under different reaction operating pressure and studies the effect of reactant ratio on catalyst selectivity.The values of reflux ratio,pressure and a series of operating parameters were determined by experiments.
