Discovery of a reactive azeotrope Nature

WebThere are higher order azeotropes – ternary and quaternary – but they are less common and more dificult to characterize. Perhaps the most famous is the water/ethanol/ benzene azeotrope (bp 64.9°), which has a lower boiling point than even the water/ethanol azeotrope (78.2°C). So one trick to making 100% ethanol (anhydrous or absolute Webbiphasic system water-2-methyltetrahydrofuran (2-MeTHF).19 Importantly, they obtained a range of pure products by simple removal of 2-MeTHF in good yields and purity, and did not use extra solvent during the work-up process.

WebThe illustration shows that the system contains four binary azeotropes (Az.1–4 in Figure 8). The blue line in Figure 8 is the liquid–liquid equilibrium line of 1-octene–water–1,4-dioxane. The lowest temperature in the system is the boiling point of the water–1,4-dioxane azeotrope, which is used as the reference temperature. Web17 mei 2024 · THF forms a homogenous minimum boiling aqueous azeotrope due to which purification by distillation is difficult. The present work has used liquid-phase adsorption of the THF–water azeotropic mixture over different adsorbents in order to purify THF.
