Oxidation of cyclohexene and alpha-pinene with O_2-H mixture in the presence of supported platinum or palladium catalysts

摘要

Oxidation of cyclohexene and alpha-pinene with an O_2-H_2 mixture in the catalytic systems contating Pt or Pd adn heteropoly compounds (HPC)was studied.The main oxidation products are expoxides,allyl alcohols,and ketones.The highest yield fo the oxidatin products was obtained in the presence of the platinum catalyst in combination wiht HPC PW_11 or PW_11 Fe.The reaction mechanism wa proposed.A relationship between the HPC composition and the nature of intermediates involved in oxidation was examined.
