Procedure

In 10 liter of methanol were dissolved 50 g of catechol and 50 g of 4-aminodiphenylamine to prepare a solution, to which triethanolamine was added to adjust the pH to 8.0. To the resulting mixture, 30 g of 30% aqueous hydrogen peroxide was added, followed by reaction at 130° C. for 5 hours. The reaction mixture obtained was cooled to give a solution of catechol-4-aminodiphenylamine condensate in methanol.
