| Abstract | ||||
| Conductivity, density, refractive index and ultra-violet of 1-Allyl-3-methylimidazolium chloride (AMImCl)and 1-butyl-3-methylimidazolium hexaflourophosphate (BMImPF6) 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 and ultra-violet measurements were used to assess the critical micelle concentration (CMC) of (AMImCl) and (BMImPF6). The CMC was found to increase as the alcohol mole fraction increased in all solvents used. The results indicate that the CMC of (AMImCl) and (BMImPF6) methanol, ethanol, and glycerol, in that order. Micellization was discovered to be a naturally occurring process. The molal volume of the two surfactants was calculated and discussed based on the density information. The polarizability and molal refraction of AMImCl and BMImPF6 were also measured and discussed using the refractive index results. For all calculations, a computer programmer was used. | ||||
