Webb13 apr. 2024 · Polyvinyl alcohol (PVA) pervaporation (PV) membranes have been extensively studied in the field of ethanol dehydration. The incorporation of two-dimensional (2D) nanomaterials into the PVA matrix can greatly improve the hydrophilicity of the PVA polymer matrix, thereby enhancing its PV performance. In this work, self … WebbThe boiling point of ethanol at one atmosphere is 78.5°C. The boiling point of the ethanol : water azeotrope is 78.2°C. The implications for separation by distillation are obvious. As the azeotrope boils at a lower temperature than either pure ethanol or pure water, it is impossible to distil pure ethanol.
