Abstract: The compositions of the vapor-liquid equilibria have been obtained in a small capacity recirculating still for the binary mixtures composed of propyl methanoate with n-alkanes (heptane, octane, nonane) and n-alkanols (ethanol, propanol, butanol) at a constant pressure of 101.32 ±0.02 kPa. Experimental data were thermodynamically verified and then correlated with suitable equations. The mixtures (x 1propyl methanoate + x2 n-heptane, or + x2ethanol, or + x2propan-l-ol) have an azeotrope at x1 = 0.786, 0.482 and 0.852, respectively. The predictions made by the ASOG and UNIFAC models can be considered acceptable. © 1994, The Society of Chemical Engineers, Japan. All rights reserved.
