Dehydration of tert-Butyl Alcohol in Reactive Distillation.

Advances in Organic Liquid‐Gas Chemical Heat Pumps

“…Riousx and Vannice [45] carried out an experimental investigation on vapor-phase isopropyl alcohol (IPA) dehydrogena- [47] has presented an excellent review on acetone hydrogenation under different conditions with various homogeneous and heterogeneous catalysts, and some new strategies to develop economic and environmentally benign approaches for acetone hydrogenation were also proposed. For the dehydration reaction of tert-butyl alcohol, catalysts such as ion-exchange resin, solid acid, and Amberlyst-15 can be applied [19,[48][49][50][51]. Honkela et al [50] studied the dehydration of tert-butyl alcohol to isobutylene by using an ionexchange resin catalyst in the temperature range of 333-363 K and obtained a temperature-dependent equilibrium constant for the dehydration reaction.…”

“…By using the reactive distillation technology, a complete tBA conversion of more than 99 % has been achieved in the temperature range of 323-393 K [51]. Abella et al [48] conducted an experiment on dehydration of tert-butanol in a reactive distillation column. They found that the use of the reactive distillation could facilitate a complete conversion of the tert-butanol dehydration by avoiding the strong inhibition of water.…”

“…The performance of an organic CHP can be characterized by such parameters as the upgrading temperature, specific power production, coefficient of performance (COP, i.e., enthalpy www.cet-journal.com [19,[48][49][50] Solid acid Depolymerization of paraldehyde [36], dehydration of tert-butanol [51] efficiency), coefficient of amplification (COA), and exergy efficiency. Definitions and expressions of these parameters are described in [5].…”

Étude de faisabilité de l’estérification d’un diacide par distillation réactive

“…Les réactions d'estérification constituent sans doute la famille de réaction la plus étudiée en distillation réactive (Bart et al, 1996 ;Okasinski et Doherty, 2000 ;Brehelin, 2007 ;Steinigeweg et Gmehling, 2002 ;Grob et Hasse, 2005 ;Lee et al, 2000 ;Tischmeyer et Arlt, 2004 ;Chen et al, 1999 ;Omota et al, 2003). Parmi les autres familles de réaction utilisables en distillation réactive, citons la transestérification (Bonet, 2006 ;Nishihira et al, 2000 ;Shaerfl et al, 2000 ;Lyuben et al, 2004) dont les applications augmentent dans le domaine des solvants verts et du biodiesel; les réactions d'éthérification constituent également un large vivier d'application pour la distillation réactive comme la synthèse du MTBE (Ryu et Gelbein, 2002), du TAME (Kolodziej et al, 2004) ou de l'ETBE; les réactions d'hydratation comme l'hydratation de l'oxyde d'éthylène (Steyer et al, 2002) ou la déhydratation du ter-butanol (Abella et al, 1999). Dans leur ouvrage, Lyuben et Yu (2008) proposent un inventaire de plus de 200 réactions étu-diées en distillation réactive.…”

A theoretical study of the dehydration of tertiary butanol in near-critical and supercritical water

“…More recently, a variety of other methods have been studied [13][14][15][16][17]. It is commonly produced in industry by an endothermic reaction (%9 kcal mol À1 in liquid phase [18]). The reaction is normally favoured by a high operating temperature and low pressure, although temperatures over 340 C can lead to undesired products [6].…”
