Effect of flow rate of a biphasic reaction mixture on limonene hydrogenation in high pressure CO2 / Ewa Bogel-Lukasik in Industrial & engineering chemistry research, Vol. 48 N° 15 (Août 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 15 (Août 2009) . - pp. 7060–7064 Titre : Effect of flow rate of a biphasic reaction mixture on limonene hydrogenation in high pressure CO2 Type de document : texte imprimé Auteurs : Ewa Bogel-Lukasik, Auteur ; Rafal Bogel-lukasik, Auteur ; Manuel Nunes da Ponte, Auteur Année de publication : 2009 Article en page(s) : pp. 7060–7064 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Overall  flow  rate  Biphasic  reaction  mixture  Limonene  hydrogenation Résumé : In this work the effect of the overall flow rate of the biphasic reaction mixture on hydrogenation distribution products is reported. As it was already presented by us, the reaction rate strongly correlates with the phase equilibrium existing in the system. On the other hand, carbon dioxide is nonreactive; nevertheless by its presence it changes the energy balance. The catalytic performance in four kinds of overall flow rate conditions (1.3, 3.3, 5.3, and 7.3 mL/min) was compared under fixed hydrogen (2.5 MPa) and total pressure (12.5 MPa). The appearance of isomers of limonene and partially hydrogenated products significantly rely upon the flow rate used in the reaction. The 1% Pd SCN catalyst used in the reaction gave the final products trans- and cis-p-menthane in a 2/3 to 1/3 molar ratio.
