Abstract
Background: The study of various physical behavior of macromolecules in solution is important in understanding the mechanism of transport process. Therefore, our keen intreset to study of various physical parameters of Cu (II) surfactants in benzene a non –polar solvent.
Objective: The present work deals with the study of density, molar volume, apprent molar volume of copper surfactants derived from mustard oil in a binary system.
Method: Complexes derived from mustard oil with urea / thiourea / 2-amino-6-chloro benzothiazole ligand were synthesized. The synthesized complexes were characterized by elemental analysis, melting points and their IR, NMR and ESR spectral studies.
Results: The results were used to determine the critical micelle concentration (CMC), various interactions and the effect of chain length of the soap molecule in non- aqueous, non- polar solvent. The CMC values are found to decrease with increase in average molecular weight of the soap complexes. The apparent molar volume has been examined in terms of Masson equation.
Conclusion: This study helps in interpretation of solute solvent interactions, structural insight of micelle and colloidal chemical behavior in binary systems. Study of these factors is essential as it indirectly makes them responsible for their immense applicability in wide areas of field.
Keywords: Cu (II) soap, edible mustard oil, soap- solvent interaction, CMC, density, Masson equation.
