Limonene epoxidation was carried out in the liquid phase using Ti/KIT-6 as the catalyst and tert-butyl hydroperoxide as oxidant. The best selectivity (60%) was obtained at 50°C after 7 h of reaction, and the conversion was 23%. The main side products were carvone, carveol, 1,2-epoxylimonene diol, perillyl alcohol and p-mentha-2,8-dien-1-ol. The catalyst does not leach under reaction conditions and it can be reused after calcination at 550 ºC. The catalyst was characterized by atomic absorption, XRD, UV-vis and N 2 adsorption isotherms. RESUMEN: Se evaluó la actividad del material Ti/KIT-6 en la epoxidación de limoneno en fase líquida con hidroperóxido de terbutilo como agente oxidante. La mayor selectividad (60%) se obtuvo a 50 ºC después de 7 h de reacción con una conversión de 23%; otros productos detectados fueron carvona, carveol, 1,2-diol-epoxilimoneno, alcohol perílico y p-menta-2,8-dien-1-ol. Se encontró que el catalizador no se lixivia y que antes de reutilizarlo se debe activar a 550 ºC. El catalizador se caracterizó por análisis químico, DRX, UV-vis e isotermas de adsorción.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
