Publisher: CSIR
Abstract: The micellar properties of benzyldimethyldodecyl-ammonium bromide has been studied by conductivity method in the binary mixtures (10% v/v) of acetonitrile, dimethyl sulfoxide, tetrahydrofuran,1,4-dioxane, methanol and ethylene glycol at different temperatures ranging from 300 to 319 K. The thermodynamics of micellization i.e, Gibbs free energy (ΔGºm), enthalpy (ΔHºm), and entropy (ΔSºm) have also been determined. The increase of critical micelle concentration with solvent mixtures has been discussed on the basis of water structure, solvent properties and hydrophobic interaction.
