Reactive Distillation for Solvent Regeneration after Biphasic Carboxylic Acid Esterification
نویسندگان
چکیده
Emulsion-enhanced biphasic esterification has proven to be applicable for carboxylic acid recovery from dilute aqueous process streams. The is esterified with 1-octanol in an emulsified regime 4-dodecylbenzenesulfonic (4-DBSA) or Ni(DBSA)2 as catalyst. After phase separation, the laden solvent must regenerated. This study presents a regeneration concept based on reactive distillation transesterification of octyl ester-laden methanol. regenerated reused extraction step.

Esterification of Acetic Acid with Butanol: Operation in a Packed Bed Reactive Distillation Column
The esterification reaction between acetic acid and butanol was investigated in a reactive distillation column. The thermodynamic aspects of considered system are discussed, equilibrium constant, vapor pressures and UNIQUAC interaction parameters were investigated. Reactive distillation experiments were carried out to provide high purity butyl acetate. For this purpose, a 2 m column with nonrea...

In this work preparation of sulfonic acid functionalized magnetite encapsulated zirconia (Fe3O4@ZrO2-SO3H) has been reported. Structural, chemical, and magnetic properties of the magnetically supported catalyst have also been investigated by Fourier transform infrared (FT-IR) spectroscopy, wide angle X-ray diffraction spectroscopy (WXRD), thermal gravimetric analysis (TGA), energy dispersive X-...
متن کاملReview Modeling of Reactive Distillation Column for the Production of Ethyl Acetate through Esterification
Reactive distillation is the combination of reaction and separation in a same column. It is an attractive option whenever liquid phase reactant is in large excess. The energy requirement of the conventional column is very high and requires large recycling costs. RD column works close to the stoichiometric feed conditions thereby eliminating recycling costs and increases the efficiency of the co...

متن کاملEntrainer-enhanced Reactive Distillation
The paper presents the use of a Mass Separation Agent (entrainer) in reactive distillation processes. This can help to overcome limitations due to distillation boundaries, and in the same time increase the degrees of freedom in design. The catalytic esterification of fatty acids with light alcohols C2-C4 is studied as application example. Because the alcohol and water distillate in top simultan...
