ABSTRACT
Vapor-liquid equilibrium behavior of tolan in alcohol was measured at atmospheric pressure in the dilute composition range of tolan, with a recirculation still. Equilibrium compositions were determined with an ultraviolet spectrometer. The reliabilities of compositions in liquid and vapor, respectively, seem to be 2 x10-5 and 2 x10-7 mole fraction of tolan. The accuracies of temperature and pressure are 0.01 K and 0.01 kPa, respectively. The volatilities Ki = yi/xi of tolan at infinite dilution were determined to be 0.0033, 0.0029, 0.0031, and 0.0054, respectively, in methanol, ethanol, 2-propanol, and 1-propanol.
