Experimental and modeling vapor-liquid equilibrium for the binary systems {ethanol(1) + glycerol(2)} and {tert-butanol(1) + glycerol(2)} at high pressures
This work reports the experimental vapor-liquid equilibrium data of {ethanol(1) + glycerol(2)} and {tert-butanol(1) + glycerol(2} systems. Boiling pressures were measured using a static synthetic method over the temperature range of 423-523 K. The experimental data were fitted using the Peng Robinson equation of state (PR-EoS) coupled to classical van der Waals mixing rules, quadratic regarding the composition. Results presented in this work may be relevant in process design of glycerol etherification. (C) 2018 Elsevier Ltd.
