Abstract
The use of immobilized catalysts based on complexes of transition metals in the oxidation process has great importance nowadays. Polymeric metal complex catalysts for petrochemical processes taking place in the liquid phase are environmentally effective and safe. This paper presents the data on oxidation process of toluene in the liquid phase under mild conditions using a catalyst. A metal complex of copper (II) immobilized in hydrogel based on thermally stable copolymer of dimethylaminoethylmethacrylate and hydroxyethylacrylate (30:70) is used as the most optimal catalyst. Experiment on toluene oxidation was reproduced several times. The relative deviation of the experiment was 3-4%. According to the infrared и ultraviolet spectrum, toluene peroxide is the main product of toluene oxygenation. The conversion of toluene within 90 min was 95%.
