Isothermal vapour-liquid equilibrium data at 333·15 K and excess molar volumes of mixing at 298·15K for the binary mixtures of ethylenediamine with isomeric butanols were measured over the entire mole fraction range. The values of molar excess free energy,GmE, and excess volumes,VmE, are negative for all the four systems, indicating strong specific interactions between two unlike molecules. The branching of the alkyl chain of alcohol also affects the excess properties considerably.
