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.
