A Comparative Study of Al2O3 Fluka, Al2O3-69, Al2O3-33 and Mil-53Ga, Mil-53Al in Catalytic Epoxidation of Licarin A
Palavras-chave:
Licarin A, Aluminum oxides, Metal-Organic Frameworks, Epoxidation ReactionResumo
The present work focused on the of catalytic efficiencies of different heterogenous catalysts including three types of Aluminum oxides; Al2O3 Fluka, Al2O3-69 and Al2O3-33 and two Metal-Organic Frameworks (MOFs); Mil-53Ga and Mil-53Al in epoxidation of Licarin A with hydrogen peroxide H2O2 and the reactions were monitored by HPLC. High conversions reached 95.7% and 95.6% were obtained in the presence of Mil-53Ga and Mil-53Al respectively, while experiments using Aluminum oxides; Al2O3 Fluka, Al2O3-69 and Al2O3-33 achieved conversions of 65.5, 68.3 and 69.8%, respectively. This can be attribute to the specific coordination geometry of the catalytically active sites within MOFs.
