Density, speed of sound, viscosity, and surface tension of hexamethylenetetramine + water + ethanol ternary mixtures from T = 293.15 to 323.15 K

Abstract

This research work analyzes the behavior of ternary mixtures composed of hexamethylenetetramine, water, and ethanol in relation to the influence of composition and temperature on several physical properties such as density, speed of sound, viscosity, and surface tension. The presence of ethanol in aqueous solutions of hexamethylenetetramine causes important changes in the behavior of the liquid mixture in comparison to blends in the absence of ethanol. One of the most important effects is the elimination of the presence of temperature-resistant structures (clathrate type) only with low additions of ethanol
