Micellization, molal volume and polarizability of benzyl and allyl-methyl imidazolium ionic liquids in aqueous and alcoholic-aqueous solvents

Conductivity, density and refractive index of 1-Benzyl 3- Methyl imidazolium chloride(BzMImCl)and1-Allyl 3-Methyl imidazolium Bromide(AMImBr) ionic liquids (ILs)At 298.15 K, Mixed solvents have been tested with different mole fractions of alcohols, containing aqueous and alcoholic-aqueous (methanol, ethanol and glycerol). The conductivity and surface tension and refractive index measurements were used to assess the critical micelle concentration (CMC) of (BzMImCl) and (AMImBr). The CMC was found to increase as the alcohol mole fraction increased in all solvents used. The results indicate that the CMC of (BzMImCl) and (AMImBr) methanol, ethanol, and glycerol, in that order. Micellization was discovered to be a naturally occurring process. The molar volume of the two surfactants was calculated and discussed based on the density information. The polarizability and molar refraction of BzMImCl and AMImBr were also measured and discussed using the refractive index results. For all calculations, a computer program was used.
