Popis:	The excess partial molar enthalpies, H m E (i), in 2-butanone (BUT)-H 2 O mixtures were measured at 4.20, 20.00, and 25.00 o C (i=BUT or H 2 O). The vapor pressures were also measured by a static method at 20.00 and 25.00 o C. From the latter data, the partial pressures and hence the excess partial molar Gibbs free energies, G m E (i), were calculated by the Boissonnas method. The excess partial molar entropies, S m E (i), were then calculated at 20.00 and 25.00 o C
