| However, reactive distillation column design requires reliable kinetic data in addition to other crucial information such as phase equilibria. Methods carried out to assess the reactive distillation process feasibility are often based on residue curve maps (RCM) for non-reactive distillation, and on reactive residue curve maps (rRCM) for reactive distillation. In addition to the four pure components, three azeotropes are the singular points of the n-propyl acetate synthesis reaction rRCM (Table 1). Two of these azeotropes (PrOH/PrOAc and PrOH/H2O) are remaining from the non-reactive RCM although two others involving reactive species (PrOAc/H2O and PrOH/PrOAc/H2O which are both heterogeneous) disappear; the last singular point of this rRCM is a quaternary reactive azeotrope. The chemical equilibrium constant value has a great influence on the liquid phase stability of this point (but not on its topological stability since it is always an unstable node): when a value of 20 (Huang et al., 2005) is used, the reactive azeotrope is homogeneous, although a value of 48.8 (Okasinski and Doherty, 2000) leads to a heterogeneous reactive azeotrope. |

| However, reactive distillation column design requires reliable kinetic data in addition to other crucial information such as phase equilibria. 然而，反应蒸馏柱设计需要可靠的动力学资料以及其他关键信息诸如相平衡。Methods carried out to assess the reactive distillation process feasibility are often based on residue curve maps (RCM) for non-reactive distillation, and on reactive residue curve maps (rRCM) for reactive distillation.对非反应蒸馏，评价反应蒸馏过程可行性的方法通常是基于馀曲线图，相应的对反应蒸馏则基于反应馀曲线图。 In addition to the four pure components, three azeotropes are the singular points of the n-propyl acetate synthesis reaction rRCM (Table 1). 除4种纯物质之外，3种共沸混合物是乙酸正丙酯合成反应rRCM （表1）的奇点。Two of these azeotropes (PrOH/PrOAc and PrOH/H2O) are remaining from the non-reactive RCM although two others involving reactive species (PrOAc/H2O and PrOH/PrOAc/H2O which are both heterogeneous) disappear; the last singular point of this rRCM is a quaternary reactive azeotrope. 尽管有其他两种有关的反应物种(PrOAc/H2O和PrOH/PrOAc/H2O ，两者均为非均相)，其中2种共沸混合物(PrOH/PrOAc 和 PrOH/H2O)依然保留来自于非反应RCM的数据。The chemical equilibrium constant value has a great influence on the liquid phase stability of this point (but not on its topological stability since it is always an unstable node): when a value of 20 (Huang et al., 2005) is used, the reactive azeotrope is homogeneous, although a value of 48.8 (Okasinski and Doherty, 2000) leads to a heterogeneous reactive azeotrope.化学平衡常数赋值对这点的化学稳定性具有很大影响（但由于此点总是一个不稳定的结点，因而对其拓扑稳定性没有影响）：虽然赋值48.8导致一个非均相反应共沸混合物，赋值20时反应共沸混合物是均相的。 |
