Participants

Reaction Steps

In 10 liters of methanol were dissolved 50 g of catechol and 50 g of 4-aminodiphenylamine. The pH of the solution obtained was adjusted to 8.0 by adding triethanolamine. Subsequently, 30 g of 30% aqueous hydrogen peroxide was added to the solution. The resulting mixture was reacted at 130° C. for 5 hours, and thereafter cooled to give a solution of a catechol-4-aminodiphenylamine condensate in methanol.
