Colloid chemical behavior and micellar characteristics of Cu (II) soaps derived from sesame and soyabean oils, (fresh oils and treated for 15 and 60 min.) at high temperature in benzene have been investigated and verified by ultrasonic velocity measurement. From these values, the specific acoustic impedance Z, adiabatic compressibility βad, intermolecular free length Lf, apparent molar compressibility Øk, molar sound velocity R, primary solvation number Sn have been calculated. The results have been analyzed in terms of Masson's equation. The results have been explained on the basis of solute-solvent interactions. The decrease in β and Lf with increasing concentration of the complex is indicating that there is sufficient solute- solvent interaction due to which micellar alignment is considerably affected.

Abstract


Colloid chemical behavior and micellar characteristics of Cu (II) soaps derived from sesame and soyabean oils, (fresh oils and treated for 15 and 60 min.) at high temperature in benzene have been investigated and verified by ultrasonic velocity measurement. From these values, the specific acoustic impedance Z, adiabatic compressibility βad, intermolecular free length Lf, apparent molar compressibility Øk, molar sound velocity R, primary solvation number Sn have been calculated. The results have been analyzed in terms of Masson's equation. The results have been explained on the basis of solute-solvent interactions. The decrease in β and Lf with increasing concentration of the complex is indicating that there is sufficient solute- solvent interaction due to which micellar alignment is considerably affected.
