摘要：

The results presented in this work confirm the specific structural properties of water solutions of 2-propanol at low concentrations, discovered earlier by other methods. The mean least intermolecular distance for pure alcohol, its water solutions at different molar concentrations, and for pure water, have been determined from the angular distributions of X-ray scattering. The concentration dependence of intermolecular distances revealed an extremum for the concentration X = 0.01 which can be interpreted as due to the clatrate structure of water. This structure remains only for solutions of low concentrations of 2-propanol and is altered at concentrations higher than 0.04 molar fraction.
