Abstract
Vapor-liquid equilibrium data for the system, MeAc-MeOH, MeAc-EtOH, MeAc-n-PrOH and MeAc-n-BuOH, were measured under the atmospheric pressure. The mixture of ester-alcohol was distilled and recycled in a Smith-Bonner type apparatus for 2 hours or longer.
Using the density-composition diagrams plotted previously, x-y data were found out for each experimental run and were discussed to be correct or not, by means of Herington's consistency test, Q function-composition and activity-composition relations.
The constants of Prahl's equation were determined experimentally and were confirmed to be reasonable all over the range of composition. Ther efore, authors suggest the smoothed data of vapor-liquid equilibrium for the systems of methylacetate-alcohol.
