Results of experimental investigations of nonlinear wave propagation in water solutions of D-glucose in a range of frequencies 1,5-150 MGz, concentration 0,01; 0,025 and 0,05 m.s., pressure 0,1-200 MPa and temperatures 293 - 363 K are presented. The nonlinear properties of D-glucose solutions are investigated by methods of acousto-optics and acoustic resonance. The influence of the dissolved gas and intensity of an acoustic wave on nonlinear parameters is investigated. The experimental data are analysed in the frameworks of the relaxation theory both models of structure of water and water solutions.
