ABSTRACT

In this work experimental VLE data are presented for N-methylformamide + hexane, N-methylformamide + benzene, N-methylformamide + chlorobenzene, and N-methylformamide + acetonitrile at 363.15 K. The data were measured using a computer driven static vapor-liquid equilibrium device. The data were modeled with the NRTL excess Gibbs energy (gE) model. Activity coefficients at infinite dilution for the low boiling compound were calculated using a differential pressure method and the NRTL equation.
