Measurement and Thermodynamic Modelling of Volumeric Properties of Alkanolamine-Water Mixtures

Abstract

The densities of aqueous binary mixtures of 2-(Methylamino) ethanol were measured at temperatures in the range of (298 to 323) K. The total concentration of the amine was restricted of 40 weight %. The experimentally measured densities were correlated as a function of temperature and mole fraction and excess molar volumes and partial molar volumes of the amine at infinite dilution in water were calculated. The derived densities of aqueous binary mixtures of 2-Piperidineethanol and Piperazine and aqueous ternary mixtures of 2-Piperidineethanol and Piperazine were also correlated as functions of temperature and concentration.
