| Abstract |
Direct excess partial molar enthalpies of the two
alkoxyamines, 3-ethoxypropan-1-amine (EPA) and 3-butoxypropan-1-
amine (BPA), in water at 298.15 K were obtained in the water-rich
region at atmospheric pressure using a semiadiabatic isoperibol
solution calorimeter. Derivatives of these partial molar properties with
respect to the composition in these two systems and in this
composition region were evaluated aiming to better scrutinize the
molecular interactions and the effect of increasing chain length in this
composition domain, where interesting features were pointed out by
previous volumetric studies. The remarkable effect of hydrolysis in the
excess partial molar enthalpies in the EPA system and the results obtained in the water-rich region for both systems complement
the interpretations based on limiting partial molar, isobaric expansions and isentropic compressions previously obtained. Changes in aggregation patterns could also be identified. |
