“…Metode yang paling umum untuk pembuatan n-propil asetat adalah melalui esterifikasi n-propanol dan asam asetat yang dipanaskan dengan katalis asam kuat. Senyawa ini umumnya tersedia masih dalam bentuk campuran terner n-propil asetat/n-propanol/air, atau dengan metode distilasi reaktif [4]. n-Propil asetat tidak dapat dipisahkan secara sempurna dengan distilasi sederhana dari campuran terner tersebut.…”

Pemisahan n-propil asetat dari campuran terner n-propil asetat/n-propanol/air merupakan salah satu proses yang tidak dapat dilakukan dengan distilasi sederhana. Adanya azeotrop terner minimum dari campuran tersebut menyebabkan n-propil asetat hanya dapat dipisahkan dari campuran n-propanol dan air salah satunya dengan metode distilasi ekstraktif. Distilasi ekstraktif merupakan proses vaporisasi parsial dengan menambahkan suatu agen pemisah non-volatil yang disebut sebagai sovent atau agen ekstraktif. Solvent yang digunakan dalam simulasi proses ini adalah campuran DMSO (Dimetil Sulfoksida) dan Gliserol dengan komposisi 50 % massa dengan perbandingan 1:2 untuk massa umpan kolom : solvent. Feed yang digunakan adalah n-propanol (10 kmol/jam) dan asam asetat (13 kmol/jam) masing-masing pada suhu 25°C dan tekanan 101,3 kPa. Hasil n-propil asetat terbaik diperoleh saat solvent diumpankan pada stage 5 dengan fraksi mol n-propil asetat pada distilat 0,9975 disertai dengan minimumnya energi reboiler yang digunakan pada konfigurasi kolom ini.n-Propyl acetate separation of the n-propyl acetate /n-propanol/water mixture composition can't be done by simple distillation. The existence of minimum ternary azeotrope on the mixture causes n-propyl acetate can be separated only by extractive distillation method. Extractive distillation is a partial vaporization process in the presence of a non-volatile separating agent called as solvent or extractive agent. Solvent used in the simulation process is DMSO (Dimethyl Sulfoxide)-Glycerol mixture (50% mass) with a ratio of 1: 2 for column feed : solvent. n-Propanol (10 kmol/hour) and acetic acid (13 kmol/hour) are fed into reactor (before extractive distillation process) at 25°C and 101.3 kPa, respectively. The best results of n-propyl acetate were obtained when the solvent was fed to stage 5 in which mole fraction of n-propyl acetate in distillate 0.9975 accompanied by the minimum reboiler energy used in this column configuration.

“…Elles concernent près d'une centaine de réactions rassemblées au sein d'une quinzaine de classes différentes. 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).…”

Résumé -Étude de faisabilité de l'estérification d'un diacide par distillation réactive -Cette étude propose une approche systématique de la conception d'une colonne à distiller réactive. Elle a été appliquée avec succès au cas peu étudié des réactions consécutives. L'estérification de l'acide 2 methyl glutarique par le méthanol a été traitée. Les 3 premières étapes de la méthode montrent la faisabilité de la production dans une colonne hybride avec un taux de reflux faible et la nécessité de travailler avec un excès de méthanol. Ces résultats théoriques ont ensuite été consolidés par un pilotage sur une colonne de diamètre 75 mm. Dans tous les régimes pilotés, les résultats obtenus sont significativement supérieurs à un réacteur en lit fixe même avec des excès de réactif plus importants.

“…Many researches have shown that the energy consumed by the distillation process accounts for about one-third of that of whole chemical production process [1] . Therefore, process intensification represents a dominating trend in the chemical process engineering, such as, the heat integrated distillation technology and the integration of the distillation process with other chemical process units.…”

“…It was often synthesized through the esterification of acetic acid (AC) and n-propanol (PROH) with strong sulfuric acid as catalyst. The traditional production takes reaction and distillation separation method [12][13] , that is, the reaction process and the separation process were separately carried out in a pre-reaction tank and a distillation column. Firstly, n-propyl acetate was generated by transesterification reaction or esterification reaction in the reaction tank.…”

“…On the reaction distillation technology for the production of n-propyl acetate, many scholars had done the relevant researches. Brehelin, M [12] et al systematically studied the catalytic reaction distillation process of production of n-propyl acetate. Not only the experiment of the production process of n-propyl acetate but also the simulation process were studied.…”

Abstract.A new process was designed for the transesterification of methyl acetate with npropanol. That is, reactive dividing-wall distillation column technology is used instead of conventional reactive distillation column and methyl acetate -methanol separation column to product n-propyl acetate and methanol. The reaction distillation process was simulated by Aspen Plus simulation software. N-propyl acetate and methanol are produced from the bottom of the main column and the sub-column, respectively. The influence of feed position of n-propanol (PROH) and methyl acetate (MEAC), reflux ratio and liquid phase distribution ratio on the heat duty of reboiler was investigated on the premise of the purity of n-propyl acetate is ensured. The simulation result shows that the new process has great advantages on capital cost saving, because not only the equipment occupancy space but also the investment in condenser are reduced.
