摘要：

Excess molar enthalpies H-m(E) of binary mixtures containing dimethyl carbonate or diethyl carbonate and six methyl n-alkyl ketones have been determined at 298.15 K and atmospheric pressure using a flow microcalorimeter. The systematic behaviour of H-m(E), increasing with the increase in the number of the carbon atoms in the ketone, is confirmed for all mixtures with the exception of mixtures of diethyl carbonate and 2-propanone. The experimental data have been correlated by means of the Redlich-Kister equation and results are interpreted in terms of molecular interactions, and are examined by an extended cell model.
