A Rapid Method for Obtaining Vapor-liquid Equilibrium Data: Distillate Analysis Technique as Applied to a Ternary System
Vapor-liquid equilibrium data were obtained for the system acetone-methanol-water by the distillate analysis technique. Distillate samples were analyzed in terms of refractive index and specific gravity using the analytical diagram of Griswold and Buford. Fifty-eight experimental points were obtained with a total of about 24 hours of experimental work, representing a substantial decrease in effort over conventional methods. From previous studies on the corresponding binaries, Wohl constants were calculated and used in checking the thermodynamic consistency of the ternary data. The data are sufficiently similar to those of the literature to indicate that the distillate analysis technique is applicable to ternary systems.
