Small-angle x-ray scattering study of fluctuations in 1-propanol-water and 2-propanol-water systems

摘要: Small-angle x-ray scattering (SAXS) measurements have been carried out on the 1-propanol (NPA)-water system and 2-propanol (IPA)-water at 20{degree}C. In NPA-water system, zero angle intensity, concentration fluctuation, Kirkwood-Buff parameters, Debye's correlation lengths determined various concentrations. IPA-water intensity also determined. both systems, all obtained parameters maxima about 0.2 of mole fraction alcohol. terms these mixing state systems is discussed compared with that TBA-water system.
