Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 n°15 (Août 2008) . - p. 5313–5317 Titre : Reaction kinetics for the heterogeneously catalyzed esterification of succinic acid with ethanol Type de document : texte imprimé Auteurs : Aspi K. Kolah, Auteur ; Navinchandra S. Asthana, Auteur ; Dung T Vu, Auteur Année de publication : 2008 Article en page(s) : p. 5313–5317 Note générale : Bibliogr. p. 5316-5317 Langues : Anglais (eng) Mots-clés : Succinic acid -- sterification  Ethanol  Kinetic model Résumé : The reaction kinetics of the reversible esterification reaction of succinic acid with ethanol to form monoethyl and diethyl succinate are presented. The reaction was studied in batch isothermal experiments catalyzed by macroporous Amberlyst-15 ion-exchange resin. Experimental data were obtained between 78 and 120 °C at different mole ratios of ethanol to succinic acid and at ion-exchange resin catalyst concentrations from 1 to 5 wt % of solution. Kinetic modeling was performed using a pseudohomogeneous mole fraction model which acceptably fits the experimental data. The kinetic model is useful for the design and simulation of processes such as reactive distillation for diethyl succinate formation.
