原始语种摘要: Density, viscosity, ultrasonic velocity and refractive index measurements of Glycerol Monostearate (GMS) in 80/20 (% v/v) benzene-methanol mixture at 290 K with varying concentrations have shown that there is noticeable variation in aggregation of non-ionic surfactant at Critical Micellar Concentration (CMC). Density and viscosity results have been satisfactorily explained by some well-known equations viz. Jones-Dole, Moulik, Vand, Einstein and Root. Jacobson model has been used to evaluate adiabatic compressibility, molar compressibility, solvation number molar sound velocity, relaxation strength, relative association and other allied acoustical constants. The variation of refractive index with concentration of GMS solutions shows a marked change in value at CMC. Treatment of data...
