Urea hydroperoxide (carbamide hydroperoxide) and melamine hydroperoxide (2,4,6-triamino- 1,3,5-triazine hydroperoxide) are adducts of hydrogen peroxide and urea/melamine. The process of preparation of urea/melamine hydroperoxide consists in addition of hydrogen peroxide solution to urea/melamine by spraying H2O2 solution onto agitated urea/melamine powder bed. The addition is carried out at sub-atmospheric pressure. Both urea hydroperoxide and melamine hydroperoxide feature good oxidative, bleaching and disinfecting properties. Under a research project scheduled for 2000-2002, development department of Zaklady Azotowe "Puławy" S.A. and Industrial Chemistry Research Institute jointly carried out tests in a pilot plant built in Puławy to develop a process for the preparation of urea hydroperoxide and melamine hydroperoxide. As a result, high quality products were obtained, which were positively assessed by potential customers.
