DENSITIES AND EXCESS MOLAR VOLUMES OF BINARY-MIXTURES CONTAINING DIETHYL CARBONATE PLUS LINEAR OR CYCLIC-KETONES AT 298.15-K

Excess molar volumes, VE,, for binary mixtures containing diethyl carbonate + 2-propanone, + 2-butanone, + 2-pentanone, + 2-hexanone, + 2-octanone, + 2-undecanone, + cyclohexanone, + 2-methylcyclohexanone, or + 2,6-dimethylcyclohexanone have been determined from density measurements at 298.15 K using an Anton Paar DMA 60/602 vibrating density meter. Mixtures of diethyl carbonate with linear ketones show a regular increase of V-m(E) with the ketone chain length. Irregular trends and lower values of V-m(E) are displayed by the diethyl carbonate + cyclic ketones. Results have been correlated by means of the Redlich-Kister equation.
