[求助] 求助翻譯一段化學英文文文獻

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，反應蒸餾柱設計需要可靠的動力學資料以及其他關(guān)鍵信息諸如相平衡。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.對非反應蒸餾，評價反應蒸餾過程可行性的方法通常是基于馀曲線圖，相應的對反應蒸餾則基于反應馀曲線圖。 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種純物質(zhì)之外，3種共沸混合物是乙酸正丙酯合成反應rRCM （表1）的奇點。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. 盡管有其他兩種有關(guān)的反應物種(PrOAc/H2O和PrOH/PrOAc/H2O ，兩者均為非均相)，其中2種共沸混合物(PrOH/PrOAc 和 PrOH/H2O)依然保留來自于非反應RCM的數(shù)據(jù)。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.化學平衡常數(shù)賦值對這點的化學穩(wěn)定性具有很大影響（但由于此點總是一個不穩(wěn)定的結(jié)點，因而對其拓撲穩(wěn)定性沒有影響）：雖然賦值48.8導致一個非均相反應共沸混合物，賦值20時反應共沸混合物是均相的。
