Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 4 (Fevrier 2010) . - pp 1526–1529 Titre : Oxypropylation of rapeseed cake Residue generated in the biodiesel production process Type de document : texte imprimé Auteurs : Serrano, Luis, Auteur ; Alriols, Maria Gonzalez, Auteur ; Briones, Rodrigo, Auteur Année de publication : 2010 Article en page(s) : pp 1526–1529 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Oxypropylation  Biodiesel  Propylene  oxide. Résumé : he oxypropylation of rapeseed cake residue generated in the biodiesel production process was studied. The reaction was carried out by suspending the rapeseed cake residue in propylene oxide [30/70 ratio (w/v)] in the presence of a basic catalyst (10% KOH) and heating the resulting mixture at 160 °C in a nitrogen atmosphere. The chemical structure of the obtained polyol was studied by CHNS elemental analysis, infrared spectroscopy, and 1H NMR spectroscopy, and other parameters such as viscosity, OH number, molecular weight (GPC), and thermal behavior (DSC, TGA) were also measured. The obtained results showed an almost total conversion of the solid substrate into a polyol with good characteristics (OH number, 610 mg of KOH/g; viscosity, 84.23 Pa·s; and molecular weight, 33550 g/mol) for use in polyurethane, polyether, or polyester formulations.
