Viscometric study of glycine, ?±-alanine and ?²-alanine in aqueous and aqueous D-glucose solutions at different temperatures

Abstract

The viscosity values of glycine, α-alanine and β-alanine have been determined in aqueous and aqueous D-glucose solutions at four different temperatures ranging from 298.15K to 313.15K at 5K intervals. The viscosity data have been analyzed by means of Jones-Dole equation to obtain Falkenhagen co-efficient,A and Jones-Dole co-efficient, B, free energy of activation of viscous flow per mole of solvent, Δμ1 0*and solute, Δμ2 0* and enthalpy, ΔH*and entropy of activation, ΔS*,of viscous flow. These parameters are discussed in terms of solute-solute, solute-solvent and solvent-solvent interactions.
