Thermodynamics of Mixtures Containing a Strongly Polar Compound. 9. Liquid—Liquid Equilibria for ε-Caprolactam + Selected Alkanes

摘要: The coexistence curves of the liquid−liquid equilibria (LLE) for (e-caprolactam + heptane), octane), nonane), decane), and 2,2,4-trimethylpentane) have been determined by critical opalescence with a laser scattering technique. All show an upper solution temperature (UCST) rather horizontal top, their symmetry depends on size alkane. UCST increases almost linearly chain length For octane mixture, is lower than including 2,2,4-trimethylpentane.
