WebIn this work, the four as-prepared ChCl: saccharides were evaluated at varying mass percentages of water, 0, 10, 20, and 30 wt.%. Physical properties were analyzed, including pH, which tended to be neutral, conductivity, and refractive index, which was about 1.5 nD for the ChCl: saccharide NADES prepared at different conditions. The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber.
