Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 19 (Octobre 2011) . - pp. 11073-11086 Titre : Transesterification of dimethyl carbonate with ethanol to form ethyl methyl carbonate and diethyl carbonate : a comprehensive study on chemical equilibrium and reaction kinetics Type de document : texte imprimé Auteurs : Tobias Keller, Auteur ; Johannes Holtbruegge, Auteur ; Alexander Niesbach, Auteur Année de publication : 2011 Article en page(s) : pp. 11073-11086 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Kinetics Chemical equilibrium Transesterification Résumé : This article studies the consecutive transesterification of dimethyl carbonate with ethanol to form ethyl methyl carbonate and diethyl carbonate. The chemical equilibrium and reaction kinetics of this system are investigated experimentally and theoretically. To enhance the reaction rate, the homogeneous catalyst sodium ethoxide was applied. Molar-based and activity-based chemical equilibrium constants were calculated from experimental results, and their temperature dependence was described using the van't Hoff equation. An activity-based kinetic model that considers the temperature dependence of the reaction rate constants with the Arrhenius equation was derived.
