Abstract

The coexistence curves of (nitrobenzene + hexadecane) have been determined within 10.5K from the critical temperature by measurements of refractive index. The critical exponent β deduced from temperature-refractive index (T, n), temperature-mole fraction (T, x), and temperature-volume fraction (T, φ) curves are consistent with the theoretical predictions. The results also been analyzed to obtain equations of coexistence curves and to discuss the goodness of selected order parameters.

Key words: NITROBENZENE, REFRACTIVITY, CRITICAL EXPONENT, DIOCTYL
