PROBLEM TO BE SOLVED: To provide an antioxidant having a low discolaration characteristics and capable of being synthesized at a low price by obtaining a specific single article and at the same time producing the antioxidant of their mixture for improving the anti-oxidation activity to elevate the anti-oxidation capability without requiring the separation of only one compound. SOLUTION: This method for producing the antioxidant is to produce phenols having at least >=1 ortho or para-substituting group from hydroxyl groups from a hydroxyl group in the presence of dialkylamine catalyst, and a phenol substituted by an alkylthiomethyl group is obtained by reacting formaldehyde and monomercaptane with the above phenols. |
