Resumo

In this work, densities, excess molar volumes, partial molar volumes and excess partial molar volumes for binary liquid mixtures of furfural and 2-methylfuran with 1-propanol or 2-propanol or 2-butanol or 1-pentanol or 2-pentanol or 1-hexanol at 298.15 K and 0.1 MPa over the entire range of composition were determined. Excess molar volumes were correlated with Redlich-Kister equation with average absolute deviations smaller than 0.0164. Excess molar volumes were negative for furfural + 1-propanol or 2-propanol and positive for all other studied binary systems. Solute partial molar volumes determined increase as alcohol carbon chain length increase, except for furfural + 2-pentanol, which presented smaller values than 2-butanol for molar fractions below 0.2. A maximum/minimum was observed from the excess partial molar volume plots. FTIR spectra data indicate bands at 3135 cm(-1), for furfural systems, and 3122 cm(-1) for 2-methylfuran systems, are related to the behavior found for excess molar volumes and that H-bonds are smaller for furfural systems than for 2-methylfuran.
