Selective preparation of campholenic aldehyde over heterogenized methyltrioxorhenium
Original language description
The presented report focuses on the isomerization of a-pinene oxide over methyltrioxorhenium (MTO) immobilized on a range of mesoporous materials with different SiO2/Al2O3 ratios, namely mesoporous alumina (m-Al2O3), aluminosilicates type Siral (with Alcontent 60-80 %), silica and MCM-41 or in its homogeneous form. Optimization of MTO immobilization has been studied and published previously. a-Pinene oxide, an oxygenated derivative of a-pinene, isomerizes rapidly into various valuable substances usefulas flavors, fragrances and pharmaceutical compounds. Campholenic aldehyde is the one of the most desired products of a-pinene oxide isomerization, being a valuable intermediate for the production of sandalwood-like fragrances. The prepared catalytic systems were successfully used for selective preparation of campholenic aldehyde. Homogeneous and heterogenized MTO showed very high activity in a-pinene oxide isomerization (100 % conversion within a few minutes) and very high selectivity t
