Excess thermodynamic properties of binary mixtures of ethanolamine-n-alkanols at 30°C

Abstract

Excess thermodynamic properties like excess molar volumes (V^E), excess viscosities (<em>η</em>^E) of binary mixtures of different compositions of ethanolamine-<em>n</em>-alkanols have been measured at 30° ± 0.01ᵒC. V^E values are positive for mixtures rich in alcohols and become negative with increase in ethanolamine content. The V^E for these mixtures follow the order: ethanol < 1propanol < 1-butanol < 1-octanol < 1-nonanol. The <em>η</em>^Evalues depend on the mole fraction and the size of the alcohol. The negative <em>η</em>^E follow the order: methanol > ethanol > 1-propanol > 1-butanol > 1-octanol > 1-nonanol.
