Vapor–liquid equilibria and excess volumes of the binary systems ethanol+ethyl lactate, isopropanol+isopropyl lactate and n-butanol+n-Butyl lactate (cas 138-22-7) at 101.325kPa

Add time:09/30/2019    Source:infona.pl

Isobaric vapor–liquid equilibrium data have been experimentally determined at 101.3kPa for the binary systems ethanol+ethyl lactate, isopropanol+isopropyl lactate and n-butanol+n-butyl lactate. No azeotrope was found in any of the systems. All the experimental data reported were thermodynamically consistent according to the point-to-point method of Fredenslund. The activity coefficients were correlated with the NRTL and UNIQUAC liquid-phase equations and the corresponding binary interaction parameters are reported. The densities and derived excess volumes for the three mixtures are also reported at 298.15K.
