| The combination of reaction and distillation in one reactive distillation (RD) unit can lead to significant reduction of investment and operational cost. However, interactions between reactions and separation increase complexity and require a better understanding of the process. Whereas RD is intensively studied for years, only few works have been published on vapour–liquid–liquid (VLL) systems, thus our investigations focus on VLL reactive systems. Experimental investigations have already been published for the production of butyl acetate (Steinigeweg and Gmehling, 2002) or amyl acetate (Chiang et al., 2002) but, to the best of our knowledge, none for n-propyl acetate reactive distillation; thus, information about n-propyl acetate synthesis can hardly be found in literature. Investigations on reactive membrane separation have led Huang et al. (2005) to publish data on chemical equilibrium. Bart et al. (1996) have published a kinetic modelling of the n-propyl acetate synthesis catalysed by an ion exchange resin (Dowex) as well as Steinigeweg (2003) with the Amberlyst-15. Unfortunately, uncertainty remains on the chemical equilibrium constant value. Finally, no data about reactive distillation pilot-plant experiments is published. |

在一個(gè)反應(yīng)蒸餾(RD)單元里，將反應(yīng)與精餾相結(jié)合,可以有效降低投資和運(yùn)營(yíng)成本。然而,反應(yīng)和分離之間的相互作用增加了反應(yīng)復(fù)雜性而且要求有更好的理解的過(guò)程。而對(duì)于反應(yīng)蒸餾(RD)單元的研究已進(jìn)行了許多年,但只有少數(shù)的作品發(fā)表在vapour-liquid-liquid(VLL)系統(tǒng),因此使我們的研究集中在VLL反應(yīng)系統(tǒng)中。對(duì)于生產(chǎn)醋酸丁酯(Steinigeweg和Gmehling,2002)或醋酸戊酯(2002年)的實(shí)驗(yàn)研究已經(jīng)公布，但是,據(jù)我們所知,沒(méi)有對(duì)乙酸正丙酯進(jìn)行反應(yīng)蒸餾;因此,很難查到有關(guān)合成醋酸正丙酯的文獻(xiàn)�？疾斓幕A(chǔ)上,黃2005在化學(xué)平衡上公布無(wú)功膜分離的有關(guān)數(shù)據(jù)。巴特1996已經(jīng)出版了動(dòng)力學(xué)建模的一種離子交換樹(shù)脂(Dowex)的有關(guān)信息，同樣Steinigeweg在2003用Amberlyst-15促合成乙酸正丙酯。不幸的是,不確定性仍然是化學(xué)平衡常數(shù)的價(jià)值。最后,還沒(méi)有對(duì)有關(guān)反應(yīng)蒸餾實(shí)際生產(chǎn)規(guī)模試驗(yàn)的數(shù)據(jù)發(fā)表。 |
