The density for mixtures of ethylenediamine (EDA) and water at a pressure of 0.2 MPa have been measured with a vibrating tube densitometer at temperatures in the range (283 to 353) K. The entire composition range was covered with intervals of molar fractions of 10 %. The excess volume has a minimum at a molar fraction of water of 59 %. The variation with temperature in excess volume is small, whereas the temperature variation in density is complex. The temperature dependence in density is well described by combining a Redlich-Kister model for excess volume, without temperature-dependent parameters, with models for the pure component densities.
