Viscosity coefficient and activation parameters for viscous flow of a homologous amino acids in aqueous xylose solutions

Partial molar adiabatic compressibilities and viscosities of some amino acids in aqueous glycerol solutions at 298.15 K

positive partial molar adiabatic compressibilities of transfer at infinite dilution, ∆tr o s 2 , κ , have been observed for the studied amino acids (except at lower concentration up to ≈ 0.6 mB in some cases), and their magnitude increases with increase in concentration of glycerol. B-coefficient of transfer, ∆trB, values are positive for these amino acids, which after passing through maxima ≈3...

Partial Molal Volume, Partial Molal Compressibility and Viscosity B-coefficient of Four Homologous -amino Acids in Aqueous Sodium Fluoride Solutions at Different Temperatures

Thermodynamic Parameters Modeling of Viscous Flow Activation in Ethylene Glycol-Water Fluid Systems

Calculation of excess quantities of ethylene glycol + water binary fluid systems at seven absolute temperatures (293.15 to 353.15) K from experimentally determined values of density and shear viscosity were presented in previous work. The examination of related functions beside the quality of correlation from several equations on these experimental values has also been reported. Considering...

Application of Genetic Programming to Modeling and Prediction of Activity Coefficient Ratio of Electrolytes in Aqueous Electrolyte Solution Containing Amino Acids

Genetic programming (GP) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. The genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. In this paper the systems containing amino ac...

Thermodynamic Study of L-alanine in Aqueous Solutions of 1-Hexyl-3-Methylimidazolium Ibuprofenate as an Active Pharmaceutical Ingredient Ionic Liquid (API-IL)

The present work reported density, viscosity, speed of sound, electrical conductivity and refractive index data of L-alanine in the aqueous solutions of 1-hexyl-3-methylimidazolium ibuprofenate at T= 298.15 K. Using the measured data, partial molar volume of transfer ( ), partial molar isentropic compressibility of transfer ( ), viscosity B-coefficient of transfer (∆traB), ion association const...
