Abstract

Densities of binary mixtures composed by N,N-dimethylformamide (DMF) and ethanolamine (EA) or N,N-diethylethanolamine (DEEA) were studied. Measurements were made by means of a vibrating tube densimeter (VTD) at temperatures from 293.15 to 313.15 K at atmospheric pressure (73 kPa). Both binary systems were measured over the full range of compositions along with the pure compounds. Excess molar volumes were calculated from the experimental densities, and were fitted to a Redlich-Kister type equation. The excess molar volumes are positive for both systems. Partial molar volumes and partial excess volumes were obtained from the Redlich-Kister equation.
