| Abstract: | Volume changes on mixing of binary systems formed by 1,2-dichloroethane andn-alcohols, namely, ethanol,n-propanol,n-butanol,n-pentanol andn-hexanol were measured as a function of composition at 30, 35, 40 and 45 °C. At all compositions theV
E values are all positive for all systems. The molar excess volumes of mixing for equimolar mixtures increase as the length
of carbon chain increases.V
E becomes more positive on increasing temperature. The positive value of the excess volume has been attributed to breaking
of hydrogen bonds of associated species of alcohol by dilution with 1,2-dichloroethane. |
