DENSITY, EXCESS VOLUMES, AND PARTIAL VOLUMES OF THE BINARY SYSTEMS OF ETHENYL ETHANOATE+BUTANOL, 2-BUTANOL, 2-METHYL-1-PROPANOL, AND 2-METHYL-2-PROPANOL AT 298.15 K

ABSTRACT Densities of the binary systems of ethenyl ethanoate (vinyl acetate) with 1-butanol,2-butanol (sec-butanol), 2-methyl-1-propanol (iso-butanol), and 2-methyl-2-propanol (tert-butanol) have been measured as a function of the composition, at 298.15 K and atmospheric pressure, using an Anton Paar DMA 5000 oscillating U-tube densimeter. The calculated excess volumes were correlated with the Redlich-Kister equation and with a series of Legendre polynomials. The excess volumes are positive for the four binaries and became larger as the alcohol becomes more branched.
