Vapor-Liquid Equilibria of CH₃CN-α-Picoline Mixtures under 760mmHg.

Abstract

Vapor-liquid equilibria of CH₃CN-α-picoline mixtures were studied, using materials purified by batch distillation. Their boiling points under 760mmHg and the refractive indices obtained are tabulated in Table I. An Othmer type apparatus with some modifications6) was employed for getting equilibrium boiling data, which are tabulated in Tables III and IV. Figs. 2 and 3 are graphic representations of Table III. The determination of the mixture compositions was made by means of refractive indices at 30°C, for which Fig. 1, a graphic representation of Table II, was employed.
