Creation of new catalytic systems of highselective oxidation reactions and use of harmless oxidizers owing to which it was possible to exclude use of the technological processes, polluting an environment and breaking of existing in the nature material and power balance, actually is philosophy of new chemistry, Green Sustainable Chemistry. In the oxidation reactions presented by us, have tried to realize the ideas of Green Chemistry by use of biomimetic catalysts of selective oxidation and use hydrogen peroxide as soft, concerning cheap and ecologically safe oxidizer (H2O2 as is known, concerns to group of green oxidizers).
Biomimetic catalysts of monooxygenation, being imitating models of monooxygenase enzymes, have been synthesized on the basis of ironporphyrin complex derivatives, immobilized on firm carriers of the acid – base nature. These biomimics have been researched in reactions of oxidation (hydroxylation) of CH4, C2H6 and С3H8 by hydrogen peroxide. As rather moderate temperature (180 – 240°C) occurs the hydroxylation of hydrocarbons with selectivity 98-100% and high enough yields of target products.
Alongside with questions of activation and stabilization of synthesized biomimetic catalysts such as PPFe3+OH/AlSiMg, PPFe3+OH/Al2O3, PPFe3+OH/NaX, TPhPFe3+OH/Al2O3 and per-FTPhPFe3+OH/Al2O3, mechanism of their action on proceeding of reactions have been investigated.
Presented Wednesday 19, 13:30 to 15:00, in session Catalysis (T2-13P).
