Excess molar volume of acetonitrile + alcohol systems at 298. 15 K. - Part II: Correlation by cubic equation of state

Abstract

The excess molar volume VE of the binary liquid systems acetonitrile methanol and acetonitrile + ethanol, experimentally determined in the previous part, were correlated by the PRSV CEOS coupled with the vdW and TCBT mixing rules. The results obtained show that the number and position of the interaction parameters of these models are of great importance for a satisfactory fitting of VE data.

Dopunska molarna zapremina VE binarnih tečnih smeša acetonitril + metanol i acetonitril + etanol, eksperimentalno određena u prethodnom delu rada korelisana je pomoću PRSV jednačine sa vdW i TCBT pravilima mešanja. Dobijeni rezultati pokazuju da je broj i položaj interakcionih parametara u razmatranim modelima od velike važnosti za zadovoljavajuće korelisanje VE podataka.
