Volumetric and viscometric studies of copper soap urea complex derived from various vegetable oils in methanol benzene mixture

Abstract

The density and viscosity of Cu (II) soap urea complex derived from four edible oils (mustard, groundnut, sesame, soyabean) in non-aqueous solvents of varying composition has been determined at constant temperature. The results were used to determine the critical micelle concentration (CMC), soap-solvent interactions and the effect of chain length of the soap urea complex molecule on various parameters. The CMC values in higher volume % of methanol are higher those in higher volume % of benzene, with regards to chain length of the soap urea complex CMC value follow the order: CSoU>CSeU> CGU > CMU The conclusions with regard to soap- urea complex and soap- solvent interaction have been discussed in terms of well-known Masson’s and Jones- Dole equations. This vital information plays an important role in various industrial and biological applications.
