Oxidation Catalytic Processes For A Cleaner Environment

In order to address the nowadays challenges faced by the Circular Economy frame, biomass is the most promising renewable carbon source alternative to oil and coal. In this raw material, terpenes are prominent molecules since they show double bonds able to be oxidized for giving rise epoxides, appealing building-blocks for the preparation of a wide variety of commodities as well as fine products. In addition, sulfide oxidation is currently of much interest because it is related with a new alternative for the desulfurization of fuels that allow to avoid the use of hydrogen. Then, getting the oxidation process in mild conditions and catalytically could be an interesting way of biomass transformation.
In our group we possess a strong expertise in the tailoring of molecular catalysts for polymerization, hydrogenation and oxidation processes. In particular our research is focused in the design and synthesis of new metal transition species containing cyclopentadienyl and silsesquioxane ligands. Recently, we have observed these types of systems oxidize terpenes and using a benign oxidant as hydrogen peroxide and in mild experimental conditions, at room temperature.
Our specific facilities are fully equipped laboratories for the synthesis and characterization of the catalysts and for studying catalytic processes. In particular the facilities we have are:
– A laboratory with all the necessary equipment for performing synthesis in air and under argon atmosphere, including two glove boxes.
– High pressure reactors, able to reach pressure up to 90 bar.
– Single crystal-X ray diffractometer.
– Spectroscopy of NMR, IR and VIS-UV. Mass spectrometry.
– GC and HPLC equipment.
