Styrene production through 1-phenylethanol vapor-phase dehydration in a new reaction system / Juan P. Perez Valencia in Industrial & engineering chemistry research, Vol. 50 N° 9 (Mai 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 9 (Mai 2011) . - pp. 5485–5489 Titre : Styrene production through 1-phenylethanol vapor-phase dehydration in a new reaction system Type de document : texte imprimé Auteurs : Juan P. Perez Valencia, Auteur ; Estanislao San Nicolas Sayans, Auteur Année de publication : 2011 Article en page(s) : pp. 5485–5489 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Styrene  Phenylethanol Résumé : This work describes an improved new reaction scheme for catalytic alcohol dehydration to the corresponding alkene, particularly as applied to styrene monomer production from 1-phenylethanol. The reaction was carried out in a bubble column containing an ionic liquid acid catalyst, which remains in liquid phase at the reaction conditions. The catalyst was set in a bubble tray and jacketed for heat supply, and a vapor containing the alcohol was fed through it. Good reaction control and high selectivity to styrene monomer (>97%) were achieved. Reduced ethylbenzene production (selectivity <0.01%) and ether and styrene oligomer formation (negligible) were observed compared to conventional systems.
