Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 7 (Avril 2009) . - pp. 3268–3270 Titre : Epoxidation of methyl oleate using heterogeneous catalyst Type de document : texte imprimé Auteurs : Paulo A. Z. Suarez, Auteur ; Mírian S. C. Pereira, Auteur ; Kenneth M. Doll, Auteur Année de publication : 2009 Article en page(s) : pp. 3268–3270 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Alumina Catalytic activity Methyl oleate Hydrogen peroxide solution Résumé : In this work, we studied the catalytic activity of commercial alumina, and laboratory-synthesized alumina doped with Lewis acid metals, in the epoxidation of methyl oleate with aqueous hydrogen peroxide. It was observed that the reaction yields increased when the amount of catalyst, the quantity of hydrogen peroxide, the concentration of the hydrogen peroxide solution, or the surface area of the catalyst was increased. Reaction yields decreased when the surface acidity of the alumina was modified by doping with Lewis acid metals.
