Light scattering spectra have been observed for binary solutions of acetone and water at 24, 34, and 44 °C in the concentration range of 0≤<I>x</I><SUB>AC</SUB>≤0.25, where <I>x</I><SUB>AC</SUB> is the mole fraction of acetone. The hypersonic velocities and the adiabatic compressibilities at 4.5 GHz were obtained from the observed values of Brillouin shifts. The observed concentration and temperature dependencies of the adiabatic compressibility were interpreted by assuming the existence of clathrate hydrate-like local structures in the solutions. The adiabatic compressibilities for binary solutions of <I>t</I>-butyl alcohol (TBA) and water were used as reference data. A comparison is made between the local structure formed in the acetone–water solution and that in the TBA–water solution.
