The enthalpies of transfer of
tetraethylurea, TEU, from water to aqueous ethanol, EtOH, propan-1-ol, PrOH, and
acetonitrile, MeCN, are reported and analysed in terms of the Extension
Coordination Model. The analyses show that the solvation of TEU is random in the
considered solvent mixtures. It is also found that TEU interact more strongly
with EtOH or PrOH than water.
Key words: titration calorimeter, preferential solvation, tetraethylurea
