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 20 °C. 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.
