METHOD FOR SIMULTANEOUSLY QUANTIFYING COPPER INHIBITOR AND ANTIOXIDANT

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously quantifying an aminotriazole copper inhibitor and a hindered phenol antioxidant. SOLUTION: An organic substance including an aminotriazole copper inhibitor containing an acyl group and a hindered phenol antioxidant containing a carboxylate group is heated with alcohol so as to simultaneously quantify the copper inhibitor and the antioxidant by quantifying ester generated from the acryl group and ester generated from the carboxylate group.
