Abstract

The reaction of liquid-phase catalytic oxidation of alkenyl and cycloalkeyl aromatic hydrocarbons with hydrogen peroxide with the participation of a heteropoly acid of the Keggin series modified with compounds of rare earth elements was studied. The dependences of the main factors of the oxidation reaction of alkenyl and cycloalkeyl aromatic hydrocarbons on temperature, duration, amount of catalyst, and the molar ratio of hydrocarbon: hydrogen peroxide were determined. For alkenyl aromatic compounds they are as follows: reaction temperature 50–80 ℃, duration 5–8 h, molar ratio of alpha methyl styrene: hydrogen peroxide 1:2, catalyst GdPO₄ + H₃[PMo₁₂O₄₀] ∙nH₂O 1–5% of the mass of the reaction mixture, under these conditions the conversion of alpha methyl styrene is about 55%, for hydrogen peroxide 52%. For alkenyl aromatic compounds they are as follows: reaction temperature 50–80 ℃, duration 5–8 h, molar ratio of alpha methyl styrene: hydrogen peroxide 1:2, catalyst GdPO₄ + H₃[PMo₁₂O₄₀] ∙nH₂O 1–5% of the mass of the reaction mixture, under these conditions the conversion of alpha methyl styrene is about 55%, for hydrogen peroxide 52%. The selectivity for 2-phenylpropanal is 56.8%, for epoxide 30.2%, for diol 11.3%, for phenylacetone 2.0%. Higher results for alkenyl aromatic oxidation with hydrogen peroxide were achieved with the participation of the TbPO₄ + H₃[PMo₁₂O₄₀] ∙nH2O catalyst, and deeper oxidation of the diol to alpha oxyketone isomers was also achieved. The double bond in 1.2-norbornene compounds, as well as in those with the cyclohexenyl derivative, is quite strained and reacts rapidly with the addition of an oxygen group. At temperatures of 50–700 ℃, the glycol yield reaches 68–70%.
