WebBoth water + ethanol and water + n-propanol binary systems exhibit azeotropes at atmospheric pressure. However that is not the case for water + methanol. What is the difference, in terms of intermolecular interactions, that accounts for the absence of the azeotrope, since all of these alcohols are relatively small sized?

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. Molecular sieves (3A and 4A) were observed to offer better separation. 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.
