摘要：
Densities of binary mixtures of 2-chloroethanol with N,N-dimethylformamide (DMF) and water have been measured over the full range of compositions at various temperatures. From these results, excess molar volumes, V-E and excess partial molar volumes at infinite dilution, (V) over bar (E,0)(i) have been calculated. V-E for (DMF + 2-chloroethanol) mixture are positive over the whole mole fraction range and negative values are obtained for (water+ 2-chloroethanol) mixture. (C) 2005 Elsevier B.V.
