F. Comelli et al., Excess molar enthalpies of diethyl carbonate plus four butanol isomers in the range (288.15-318.15) K, J CHEM EN D, 44(4), 1999, pp. 739-743
Excess molar enthalpies H-m(E) of binary mixtures containing diethyl carbon
ate + 1-butanol, + 2-butanol, + 2-methyl-1-propanol, and + 2-methyl-2-propa
nol have been determined using a flow microcalorimeter in the range (288.15
-318.15) K and at atmospheric pressure. All mixtures are strongly endotherm
ic, with maxima of H-m(E) varying from 1900 (mixture containing 1-butanol)
to 2550 (mixture containing 2-butanol) J . mol(-1). The H-m(E) curves are n
early symmetrical and show values increasing as the temperature increases.
Data have been correlated using the Redlich-Kister equation, and experiment
al results have been qualitatively discussed.
