A series of solid base derived from porous materials supporting magnesia has been prepared by use of microwave irradiation. After supporting sulfonated cobalt phthalocyanine (CoPcS), the resulting catalysts could be used in the mercaptan oxidation reaction. By introducing additives of methanol and detergent as we invented, the catalysts display a very good activity and stability in the reaction. The promotion mechanism has been identified in this paper: methanol could extract the mercaptan from the organic phase into the aqueous phase, and it could improve the soluble ability of CoPcS in water , which increase the activity of the catalysts.
