Effect of reactive distillation on the yield of tetraacetylethylenediamine (TAED) / Eun-Seon Kim 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. 11250–11253 Titre : Effect of reactive distillation on the yield of tetraacetylethylenediamine (TAED) Type de document : texte imprimé Auteurs : Eun-Seon Kim, Auteur ; Kyun Young Park, Auteur ; Jung-Moo Heo, Auteur Année de publication : 2011 Article en page(s) : pp. 11250–11253 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Tetraacetylethylenediamine Résumé : Tetraacetylethylenediamine (TAED) was prepared by acetylation of diacetylethylenediamine (DAED) with acetic anhydride in a 5 L reactor coupled with a packed distillation column, 2.5 cm in inside diameter and 1 m in length. The reaction temperature was set at 135 °C and the reflux ratio at 6. The molar ratio of acetic anhydride to DAED was varied from 3 to 5. A TAED yield as high as 80% was obtained, higher by 15% than in the absence of distillation. The temporal variation of the TAED yield was calculated using the kinetic parameters in the literature. Calculated and experimental values showed good agreement.
