Y. Uosaki et al., EXCESS MOLAR VOLUMES OF (3-METHYL-2-OXAZOLIDINONE PLUS AN ALKAN-1-OL)AT 298.15 K, 313.15 K, AND 328.15 K, Fluid phase equilibria, 136(1-2), 1997, pp. 299-306
Excess molar volumes V-m(E) for (3-methyl-2-Oxazolidinone + an alkan-1
-ol from methanol to octan-1-ol) were obtained from density measuremen
ts over the entire composition range at 298.15 K, 313.15 K, and 328.15
K. The excess molar volumes for the binary mixtures studied at each t
emperature are negative over the whole mole-fraction range, except for
(3-methyl-2-oxazolidinone + heptan-1-ol or octan-1-ol), which exhibit
s slightly positive values of V-m(E) in the alcohol-rich region and sl
ightly negative values in the 3-methyl-2-oxazolidinone-rich region. Wi
th increasing alkyl-chain length of the alkan-1-ol, the minimum value
of V-m(E) decreases in magnitude and its location shifts to higher mol
e fraction of 3-methyl-2-oxazolidinone. Partial molar excess volumes,
(V-m(E))(1) and (V-m(E))(2), for components were also evaluated. Volum
etric properties were discussed from intermolecular interactions betwe
en like molecules or unlike molecules. (C) 1997 Elsevier Science B.V.
