LLE of binary mixtures 3-phenyl-1-propanol + alkanes

Abstract

A liquid mixture is more complex the greater the number of interactions that originate between the different active groups (functional groups): significant parts that constitute the characteristic links of the chain of each type of molecules. The determination of the liquid-liquid equilibrium (LLE) of binary mixtures is a way of approaching the study of molecular interactions. Thermodynamic stability analysis indicates that a liquid mixture separates into two liquid phases if doing so can decrease its Gibbs energy. This phenomenon is important in many separation processes such as extraction and extractive distillation. The partial miscibility is a manifestation of the non-ideal behavior of liquids and its prediction is a test for the theories of dissolutions.
