ABSTRACT
Density of three binary mixtures formed by N,N-dimethylformamide (DMF) with aromatic hydrocarbon (one of benzene, toluene, and ethylbenzene) has been determined over the full range of compositions at the temperatures range (293.15 to 353.15) K and atmospheric pressure using a vibrating-tube densimeter. From these experiments, excess molar volumes oV E mP could be calculated and fitted by the fourth-order Redlich Kister equation, so the coefficients and the standard error (r) could be got. Our result shows V E m decreases when temperature increases in the studied systems.
