Catalyst for the oxidation of sulfur-containing compounds based on a polyamide membrane modified with cobalt phthalocyanine

详细

The catalytic activity of phthalocyanine metal complex immobilized on the surface of a porous polyamide membrane is studied in the oxidation reaction of n-propyl mercaptan. Since noncatalytic oxidation is possible in the presence of oxygen, the kinetics of n-propyl mercaptan oxidation is analyzed as its aqueous alkaline solution passes through unmodified membranes. Characteristics of the catalyst’s performance are selected to evaluate the efficiency of the catalytic process. It is shown that the modified membranes with pore diameters of 1 and 2 μm are the most effective catalysts.
