R. Francesconi et F. Comelli, Excess molar enthalpies and excess molar volumes of binary mixtures containing dimethyl carbonate plus four butanol isomers at (288.15, 298.15, and 313.15) K, J CHEM EN D, 44(1), 1999, pp. 44-47
Excess molar enthalpies, H-m(E), and excess molar volumes, V-m(E), of dimet
hyl carbonate + 1-butanol, + 2-butanol, + 2-methyl-1-butanol, and + 2-methy
l-2-butanol have been determined at (288.15, 298.15, and 313.15) K and atmo
spheric pressure using a flow microcalorimeter and a digital density meter.
Excess properties are positive over the entire experimental conditions, in
creasing as the temperature increases. Maxima values of H-m(E) vary from 21
00 up to 2900 J.mol(-1). Those of V-m(E), vary from 0.57 up to 0.83 cm(3).m
ol(-1). Experimental data have been correlated using Redlich-Kister polynom
ials, and parameters from least-squares analysis have been reported.
