Densities, viscosities, and surface tensions of aqueous 2-amino-2-ethyl-1,3-propanediol solutions

Abstract

Densities, viscosities, and surface tensions of 2-amino-2-ethyl-1,3-propanediol (AEPD) + water mixtures were measured over wide temperatures ranging from (303.15 to 343.15) K. The concentration ranges of AEPD were (20-100) mass % for density measurements and 20-80 mass % for viscosity and surface tension measurements. The experimental values were correlated as a function of temperature and concentration. The average absolute deviations were found to be 0.07% for density, 0.56% for viscosity, and 0.42% for surface tension.
