Microencapsulation of epoxidized linseed oil liquid cross-linker in poly(N-vinyl-pyrrolidone) / Daniela Senatore in Industrial & engineering chemistry research, Vol. 49 N° 8 (Avril 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 8 (Avril 2010) . - pp. 3642–3653 Titre : Microencapsulation of epoxidized linseed oil liquid cross-linker in poly(N-vinyl-pyrrolidone) : optimization by a design-of-experiments approach Type de document : texte imprimé Auteurs : Daniela Senatore, Auteur ; Jozua Laven, Auteur ; Rolf A. T. M. van Benthem, Auteur Année de publication : 2010 Article en page(s) : pp. 3642–3653 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Microencapsulation  Epoxidized  Linseed  Oil  Liquid  Poly  N-vinyl-pyrrolidone Résumé : A liquid cross-linker, epoxidized linseed oil (ELO), was encapsulated in a plastic with a high glass transition temperature (poly(N-vinyl-2-pyrrolidone); PVP). The process parameters of the spray-drying employed were optimized by a Design-of-Experiments (DoE) approach. Three factors concerning both the dispersion feed (total concentration of additive and core to encapsulant ratio) and the spray-drying processes (spray flow of the spray-drier) were chosen. A full 23 factorial Design of Experiments with center point was carried out in duplicate. The aim of the Design of Experiments was to understand and to optimize the encapsulation process in terms of total amount of epoxidized linseed oil in the powder (payload) and amount of epoxidized linseed oil enclosed in the polyvinylpyrrolidone (encapsulation efficiency). The results enabled the production of a free-flowing spray-dried powder of ELO encapsulated in PVP with an encapsulation efficiency of 85%.
