ABSTRACT

Densities, q, ultrasonic speeds, u, and viscosities, g, of aqueous-1,4-butanediol (20% and 40% w/w of 1,4- butanediol) and of solutions of glycine (Gly), DL-alanine (Ala), and L-valine (Val) in aqueous-1,4-butanediol were measured at T = (298.15, 303.15, 308.15, 313.15, and 318.15) K. From these experimental results, apparent molar volume, V/, limiting apparent molar volume, V / and the slope, Sv, apparent molar compressibility, j/, limiting apparent molar compressibility, j /, and the slope, Sk, transfer volume, V /;tr, Falkenhagen coefficient, A, Jones Dole coefficient, B, free energies of activation of viscous flow per mole of solvent, Dl
