The rates of isothermal heterogeneous sucrose hydrolysis by using acid ion-exchange resin IR-120H are higher for MWH 5–7 times against the CH. The MWH does not lead to the change in the kinetics model of heterogeneous sucrose hydrolysis. The values of kinetics parameters of hydrolysis under the MWH are lower than the corresponding values under the CH.
The established decreases in the activation energy and increases in the pre-exponential factor under the MWH in comparison to the CH is explained with the increase in the energy of ground vibrational level of the –OH out-of-plane deformation in sucrose's molecule and with the decrease in its anharmonicity factor which is caused with the selective resonant transfer of energy from the energetic reservoir-heating bath to the –OH-oscillators in sucrose molecules.
