摘要：

Small-angle neutron scattering (SANS) studies of 1-propanol-heavy water mixtures were performed in the mole fraction range of 0.02-0.6 at 20degreesC. Enhanced scattering was observed in the alcohol mole fraction range 0.1-0.3 revealing the enhanced aggregation of the alcohol molecules. From the experimental data the fluctuations and the Kirkwood-Buff integrals were calculated and compared with those obtained by small-angle X-ray scattering and from thermodynamic data. It was demonstrated that SANS is a suitable method to determine the Kirkwood-Buff integrals in liquid mixtures.
