Abstract: | The excess volumes of mixing for methanol and ethanol with secondary amines (diethylamine, di-n-propylamine and di-n-butylamine) have been measured over the whole composition range at 293.15 and 323.15 K. The excess volumes have been fitted to an equation of the type $$V^E /cm^3 mol^{--1} = x \left( {1 - x} \right) \sum\limits_{n = 0}^3 { A_n \left( {1 - 2x} \right)^n } $$ The different temperature dependences of the mixtures were explained by means of the association theory. |
