摘要：

Densities of the systems of tert-butanol (TB) +n-butylamine (NBA), +di-n-butylamine (DBA) and +tri-n-butylamine (TBA) were determined between 303.15 and 323.15 K at different compositions in the range 0 <= x(2)<= 1, where x(2) is the mole fraction of butylamines BA, NBA, DBA and TBA. Excess molar volumes have been calculated from the density data. In the whole range of composition, systems of TB+NBA and TB+DBA show negative V-m(E) values, whereas the values are positive for TB+TBA. While the negative values are accounted for by the effects of specific interaction and interstitial accommodation, positive values are due to dispersive forces.
