Application of the Kirkwood-Buff formalism to CH3(CH2)n−1OH + polyether mixtures for n = 1, 2, 3

► Kirkwood-Buff integrals has been applied to CH3(CH2)n−1OH + polyether for n = 1, 2, 3. ► Alcohol self-association is weaker in polyether systems than in monoether mixtures. ► Dipolar interactions increase with the alcohol size in systems with a polyether. ► The small δij values obtained suggest that molecular distribution is nearly random. ► Preliminary calculations using the Flory model confirms this conclusion.
