Vapor−liquid equilibrium at 101.3 kPa has been determined for the
binary systems of acetone +
3-pentanone and isopropyl ether + 3-pentanone. The two systems
exhibit positive deviations from ideal
behavior. The activity coefficients were correlated by the Wilson
equation. The results are thermodynamically consistent according to the method of Van Ness. Neither
system shows an azeotrope.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
