Abstract

Abstract: The isothermal vapor liquid equilibrium data of glycine, DL-alanine and L-valine in methanol-water mixed solvents at 333 Kand 338 Khave been measured with the improved Rose still.Alinear relationship was found between the pressure and the concentration of amino acids when the binary relative composition is fixed.The extensive linear theory for the salted solution which has been established was further extended to the systems containing the non-volatile components.The linear formula has been obtained from the law of the thermodynamics.The influence laws of amino acids on the structure and property of the mixed solvent have been investigated.

Key words: Amino acids, Linear relationship, Mixed solvent, Interaction
