摘要：
In the present paper, density and kinematic viscosity have been determined for aqueous solutions of two amines (pyrrolidine and piperidine) at (20, 30, 40, and 50) degrees C. The study of these mixtures has covered its complete composition range. Density shows the typical behavior of the composition and temperature's effect, but viscosity shows a maximum with an increased amine composition. A Redlich-Kister type equation was employed to fit the excess properties.
