Vapor Liquid Equilibrium Measurement and Distillation Simulation for Azeotropic Distillation Separation of H₂O/EM Azeotrope

Separations
Since H2O and Ethylene Glycol Monomethyl Ether (EM) form a minimum-boiling azeotrope, 1-pentanol, 1-hexanol, and 1-heptanol are selected as entrainers to separate the azeotropic mixture (H2O/EM) using azeotropic distillation.
