| Resumo: | The products of the fine chemical industry have become a fundamental need to maintain current social life. Fine chemicals include pharmaceuticals, flavorings, fragrances, etc. It should be noted that many of the processes of preparation of these products generate high amounts of by-products and / or pollutant residues. One of the alternatives for the development of sustainable and less polluting processes is the use of heterogeneous catalysts. In this context, the hybrid metal-organic materials called MOFs that emerged in 2006, characterized by being crystalline and highly porous, have high potential for their use as heterogeneous liquid phase catalysts for reactions of interest to the fine chemical industry. In the present Master Final Work the catalytic activity of materials type MOF based on the family UiO-67 (Zr) (UiO: Universitetet i Oslo) has been studied. In particular, the influence of the presence of metal complexes based on bipyridines coordinated with metals (Cu2+, Co2+ and Fe3+) has been studied, acting as organic ligands of the MOF in the catalytic activity. The reaction studied has been the oxidation of indane in the absence of solvent and exclusively using molecular oxygen as an oxidizing agent. In general, the results indicate that the presence of the metal complexes in the MOF structure improves the catalytic activity. Among all the materials prepared, by pre- or post-synthetic methods, the material prepared by the pre-synthesis method using cobalt has proved to be the most active. The higher activity of this catalyst has been attributed to the high crystallinity, pore volume and surface area with respect to the other catalysts prepared. In addition, the material can be reused without appreciable loss of its catalytic activity. |
