Oxidative Desulfurization of Dibenzothiophene Catalyzed by Ionic Liquid [BMIm] HSO4 / Wei Zhang in Industrial & engineering chemistry research, Vol. 49 N° 22 (Novembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 22 (Novembre 2010) . - pp. 11760–11763 Titre : Oxidative Desulfurization of Dibenzothiophene Catalyzed by Ionic Liquid [BMIm] HSO4 Type de document : texte imprimé Auteurs : Wei Zhang, Auteur ; Ke Xu, Auteur ; Qian Zhang, Auteur Année de publication : 2011 Article en page(s) : pp. 11760–11763 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Ionic  liquid  Catalyst  Oxidative Résumé : An acidic ionic liquid N-butyl-N-methylimidazolium hydrogen sulfate ([BMIm]HSO4) was applied as extractant and catalyst for the oxidative desulfurization of dibenzothiophenes (DBT) in the presence of H2O2 in model oil. Several parameters, e.g., catalyst amount, hydrogen peroxide quantity, reaction time, and temperature, were investigated in detail. The catalytic oxidative desulfurization rate can reach 100% for DBT in model oil. The ionic liquid [BMIm]HSO4 can be recycled 5 times with only a slight reduction in activity.
