Extraction of aleuritic acid from seedlac and purification by reactive adsorption on functionalized polymers / Shobha K. Nagappayya in Industrial & engineering chemistry research, Vol. 49 N° 14 (Juillet 2010)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 14 (Juillet 2010) . - pp. 6547–6553 Titre : Extraction of aleuritic acid from seedlac and purification by reactive adsorption on functionalized polymers Type de document : texte imprimé Auteurs : Shobha K. Nagappayya, Auteur ; Vilas G. Gaikar, Auteur Année de publication : 2010 Article en page(s) : pp. 6547–6553 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Aleuritic acid Polymers Résumé : Reactive extraction of aleuritic acid from seedlac was carried out at different NaOH concentrations and temperatures. A mathematical model was proposed for the hydrolysis of seedlac considering the breaking of ester linkages at any position along the length of the polymeric chain. Recovery and purification of aleuritic acid from the product mixture was further achieved by reactive adsorption using weakly basic polymeric resin containing tertiary amino group as the functional group. Aleuritic acid was recovered by continuous column studies with 92% yield and 94% purity.
