Density and excess molar volume values of binary mixtures of 2-chloroethanol plus 1,2-ethanediol

Densities (rho) of the 2-chloroethanol + 1,2-ethanediol binary solvent syst em are presented at 19 temperatures in the -10 less than or equal to t/degr ees C less than or equal to +80 range. The measured values have been used t o test some empirical equations of the type rho=rho(t), rho=rho(X-1) and rh o=rho(t,X-1), in order to provide useful interpolation procedures to obtain calculated values corresponding to the experimental data gaps. From the pr imary data, the excess molar volumes (V-E ) have been calculated. The sign and magnitude of this quantity have been discussed in terms of the type and nature of binary interactions. Furthermore, the derived quantities have fi tted the Redlich-Kister equation with very good accuracy.
