Isobaric (vapour + liquid) equilibria were determined at p = 101.3 kPa
for(methanol + butyl acetate), (methanol + isobutyl acetate), (vinyl
acetate + butyl acetate), and (vinyl acetate + isobutyl acetate). The
thermodynamic consistency of the experimental data was checked by usin
g a modified Dechema test. The activity coefficients were correlated w
ith Margules, van Laar, Wilson, NRTL, and Wilson equations. Among the
solvents chosen as potential extractive distillation entrainers, none
shows azeotropy. It was found more appropriate to use butyl acetate as
solvent for the extractive distillation from an economical perspectiv
