EXCESS MOLAR VOLUMES OF (3-METHYL-2-OXAZOLIDINONE PLUS AN ALKAN-1-OL)AT 298.15 K, 313.15 K, AND 328.15 K

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.
