Excess molar volume of the acetonitrile + alcohol systems at 298.15K. Part I: Density measurements for acetonitrile + methanol, + ethanol systems

Abstract

The excess molar volume VE of the binary liquid systems acetonitrile methanol and acetonitrile + ethanol has been evaluated from density measurements at 298.15K and at atmospheric pressure over the entire composition range. A vibrating tube densimeter, type Anton Paar DMA 55, was applied for these measurements. The Redlich–Kister equation was used to fit the experimental VE data.
