Sk. Mehta et al., EXCESS MOLAR ENTHALPIES OF MIXTURES OF PYRROLIDIN-2-ONE WITH HIGHER ALKANOLS AT THE TEMPERATURE 303.15 K, Journal of Chemical Thermodynamics, 30(9), 1998, pp. 1095-1101
The excess molar enthalpies H-m(E) Of mixtures of pyrrolidin-2-one wit
h hexan-1-ol, or heptan-1-ol, or octan-1-ol, or nonan-1-ol, or decan-1
-ol have been measured over the entire composition range at the temper
ature T= 303.15K. The H-m(E) values are positive for all the mixtures
over the whole composition range. The values for higher alkanols incre
ase in the order hexan-1-ol < heptan-1-ol < octan-1-ol < nonan-1-ol <
decan-1-ol. The H-m(E) values have been used to calculate the excess p
artial molar enthalpies of the respective components. (C) 1998 Academi
