Selective oxidation of aromatic olefins to aldehydes with hydrogen peroxide over V-ZSM-5 catalyst

Abstract

The selective oxidation of aromatic olefins to aromatic aldehydes is efficiently employed by using hydrogen peroxide as clean oxidant in the presence of the catalyst of vanadium supported on ZSM-5. The 56.1 % of conversion for substrate styrene is obtained in 90.8 % of selectivity for product benzaldehyde. The mechanism involving an ethylbenzene peroxide active intermediate is proposed to realize the reaction. In comparison to traditional methods, the newly designed multiphase catalytic system embodies principles of green sustainable development and exhibits enhanced environmental friendliness towards a promising industrial application.
