AB Liquid-liquid equilibria phase diagrams have been determined for the systems: 2-methoxyphenol + n-decane, or+ n-dodecane, or + n-tetradecane or + n-hexadecane and for 2-ethoxyphenol + n-octane, or + n-dodecane, or +n-tetradecane, or + n-hexadecane. The experimental method used is based on the observation, by means of alaser scattering technique, of the turbidity produced on cooling when a second phase appears. All the mixturesstudied show an upper critical solution temperature, which increases with the n-alkane size. Dipolar interactionsbetween like molecules become stronger in the sequence: 2-ethoxyphenol < 2-methoxyphenol < phenol. Dataavailable in the literature suggest that this relative variation is also valid for n-alkane mixtures containing othersubstituted anilines, characterized by having a second polar group. The dependence of the upper critical solutiontemperature on the molecular structure of the polar aromatic compound involved is shortly discussed in terms ofintramolecular and steric effects.
