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

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 m...

Description
Summary: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. Dopunska molarna zapremina VE binarnih tecnih smesa acetonitril + metanol i acetonitril + etanol, odredjena je merenjem gustine na 298.15K i atmosferskom pritisku u celom koncentracionom opsegu. Merenja su vrsena digitalnim gustinomerom, tipa Anton Paar DMA 55. Za korelisanje eksperimentalnih podataka koriscena je Redlich-Kister-ova jednacina.
