ABSTRACT

Present research work analyses the behavior of aqueous solutions of hexamethylenetetramine determining several physical properties such as density, speed of sound, viscosity and surface tension. Besides the own importance of these properties they allow analyze the type of interactions between solute and solvent molecules. The study consisted on the evaluation of the influence of amine concentration and temperature upon these properties. An increase in amine concentration causes an increase in density, viscosity and speed of sound, and a decrease in isentropic compressibility and surface tension. On the basis of experimental data of isentropic compressibility and surface tension the presence of temperature resistant structure has been determined.
