Density and excess molar volumes of binary mixtures of 1,2-dichloroethane plus 2-chloroethanol from -10 to 80 degrees C

Densities (rho) were measured for the 1,2-dichloroethane (DCE) + 2-chloroethanol (CE) at 19 temperatures in the range -10 less than or equal to t/C-0 less than or equal to 80. The experimental data were used to test some empirical relations giving the dependence of the density on the temperature and binary composition: rho = rho(t), rho = rho(X-1) and rho = rho(t, X-1). From the experimental data, the excess molar volumes (V-E) were calculated. The VE values are always positive. This quantity has been interpreted in terms of geometric effects (interstitial accomodation) and possible specific interactions (hydrogen bonding and dipolar interactions) which occur between components.
