FIELD: chemistry.
SUBSTANCE: heterogeneous catalyst for liquid-phase oxidation of organic compounds contains a carrier, a glutaric dialdehyde as a cross-linking agent, and a horseradish root extract (Armoracia Rusticana) as an active ingredient. According to the invention, titanium dioxide is used as a carrier, modified in sequence with 0.095÷0.105 n solution of hydrochloric acid, 0.195÷0.205 % solution of chitosan in 0.0045÷0.0055 M hydrochloric acid solution and 4.95÷5.05 % aminopropyltriethoxysilane solution at 95.5÷96.5 % ethanol with the following component ratio, wt %: titanium dioxide 45÷55; chitosan - 7.5÷12.5; aminopropyltriethoxysilane 17.5÷22.5; crosslinking agent (glutaric dialdehyde) - 7.5÷12.5; active ingredient (horseradish root extract) - 7.5÷12.5.
EFFECT: increasing the activity, selectivity and operational stability of the heterogeneous catalyst in the liquid-phase oxidation of organic compounds by hydrogen peroxide.
