Abstract
Density of the 2-chloroethanol (CE) + 1,2-ethanediol (ED) binary solvent system are presented at 19 temperatures in the -10 < t/°C < 80 range. The measured values have been used to test some empirical equations of the type ro=ro(t), ro=ro(Xi) and ro=ro(t,Xi), in order to provide useful interpolation procedures to obtain calculated values corresponding to the experimental data gaps. From the primary data, the excess molar volumes (V^E) have been calculated. The sign and magnitude of this quantity have been discussed in term of the type and nature of binary interactions. Furthermore, the derived quantities have fitted the Redlich-Kister equation with very good accuracy. somePubblicazioni consigliate
