Abstract


In this work, the liquid–liquid and solid–liquid phase behaviour of ten aqueous pseudo-binary and three binary systems containing polyethylene glycol (PEG) 2050, polyethylene glycol 35000, aniline, N,N-dimethylaniline and water, in the temperature range 298.15–350.15 K and at ambient pressure of 0.1 MPa, was studied. The obtained temperature-composition phase dia­grams showed that the only functional co-solvent was PEG2050 for aniline in water, while PEG35000 even showed a clear anti-solvent effect in the N,N-
-dimethyl­aniline aqueous system. The experimental solid–liquid equilibria (SLE) data have been correlated by the non-random two-liquid (NRTL) model, and the correlation results are in accordance with the experimental results.
