Kinetic regularities of α-ethylacrolein and crotonic aldehyde oxidation in methanol, allyl alcohol and glycidol were studied. Rate constants of hydrogen peroxide consumption and rate constants of unsaturated acid and its ester accumulation for both aldehydes in different alcohols at various catalyst concentrations and temperatures were calculated. The reaction activation parameters were also calculated. Dependences of ester/acid ratio on the reaction conditions were ascertained. Dependence of the reaction rate and the reaction products composition on aldehyde and alcohol structures was shown. Data of the reaction products composition dependence on the reaction conditions conform to the reaction kinetic parameters.
