Measurement of Thermophysical Properties of Pure and Mixture of Alkanolamines from 288.15-323.15 K

Density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (dea) and methyl diethanolamine (mdea) with water have been measured at different temperatures from 288.15-323.15 k at atmospheric pressure. also, this study presents the effects of mixture composition and temperature upon these thermo-physical properties. to measure the density and refractive index, the amine mass percentages of binary and ternary aqueous solutions were between 5-40% and 40-80%, respectively. to determine the kinematic viscosity, the amine mass percentages for binary aqueous solutions were 5-40%. the densities, refractive indexes, and viscosities of 22 binary and ternary mixtures were finally measured
