Two-step reactive distillation process for cyclohexanol production from cyclohexene / Amit Katariya in Industrial & engineering chemistry research, Vol. 48 N° 21 (Novembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 21 (Novembre 2009) . - pp. 9534–9545 Titre : Two-step reactive distillation process for cyclohexanol production from cyclohexene Type de document : texte imprimé Auteurs : Amit Katariya, Auteur ; Hannsjorg Freund, Auteur ; Kai Sundmacher, Auteur Année de publication : 2010 Article en page(s) : pp. 9534–9545 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Cyclohexanol  Reactive  distillation  Cyclohexene Résumé : The present work deals with a novel and attractive alternative process route for the production of cyclohexanol by indirect hydration of cyclohexene using reactive distillation. The proposed two-step process comprises the esterification of cyclohexene with formic acid followed by the hydrolysis of the formed ester. The principle feasibility of this new process has recently been proved by means of residue curve analysis [Steyer et al. Ind. Eng. Chem. Res. 2008, 47, 9581−9587]. In the present contribution, detailed equilibrium stage simulations are performed to identify the optimum design and operating conditions for the coupled reactive distillation column scheme. The simulations reveal that it is possible to achieve almost complete conversion of cyclohexene to cyclohexanol with a comparatively low amount of catalyst. To the best of our knowledge, this is the first time that such an outstanding performance of a process for the production of cyclohexanol is reported.
