To study the performance of inorganic composite catalyst for the SPC oxidation of p-methyl anisole, Cu2-Co2-KBr is used as catalyst of sodium percarbonate oxidation for p-methyl anisole synthesized by paracresol methylating. Effect of reaction conditions, such as the factors of catalyst composition, catalyst quantity, solvent, reaction temperature and time on oxidation of p-methyl anisole, is investigated.

On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti-acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.
