摘要：

In this study, density, electrical conductivity, refractive index and viscosity of aqueous potassium and sodium salt solutions of alpha-aminobutyric acid were presented. Measurements were done over the temperature range (303.15 to 343.15) K and atmospheric pressure for salt compositions from x(1) = 0.009 to 0.062. A modified Graber et al. equation was used to correlate the density, electrical conductivity, and refractive index with temperature and composition leading to average absolute deviations (AAD) between the predicted and calculated values of 0.04%, 0.7%, and 0.01%, respectively. The viscosity data were represented as a function of temperature and composition via Vogel-Tamman-Fulcher (VTF) type equation at an AAD of 0.6%. (C) 2014 Elsevier Ltd. All rights reserved.
