| dc.description | RESUMEN: Se comparó la actividad de Sn-MCM-41 y Sn-SBA-15 para la síntesis de nopol a partir de β-pineno y paraformaldehído. Los materiales se prepararon por los métodos hidrotérmico y el de impregnación húmeda incipiente, utilizando cloruro estañoso como sal precursora de Sn. Los catalizadores sintetizados por impregnación presentaron mayor actividad y fueron más selectivos a nopol que los materiales obtenidos por el método hidrotérmico. La conversión de β-pineno obtenida con Sn-MCM-41 fue similar a la obtenida con Sn-SBA-15. Mediante síntesis hidrotérmica, se obtuvo especies de Sn(IV) en forma de agregados de SnO y substituyendo isomórficamente Si en la MCM-41 y la SBA-15, respectivamente. | |
| dc.description | ABSTRACT: The catalytic activity of Sn-MCM-41 and Sn-SBA-15 for nopol synthesis from β-pinene and paraformaldehyde was compared in this work. The materials were prepared by the hydrothermal and the incipient wetness impregnation methods using stannous chloride as Sn precursor. In contrast to hydrothermal methods, impregnation leads to more active and selective materials for nopol production from β-pinene. β-Pinene conversion over Sn-MCM-41 and Sn-SBA-15 was similar. In the materials obtained by hydrothermal procedures, Sn(IV) species were detected as bulk SnO in MCM-41 and 2 isomorphously substituting Si in SBA-15. | |
