Low-Frequency Acoustic Action on the Kinetics and Mechanism of First-Order and Bimolecular Chemical Reactions in a Structured Liquid Phase

Abstract

The effect of periodic mechanical action on the kinetics and the mechanism of liquid-phase reactions were studied. This is the first stage of extensive research in which mathematical modeling of simple kinetic schemes taking into account the formation of associates is planned to carry out. In case of a multistage reaction existence of several quasi stationary states and oscillations of concentration of reagent is possible.

At a research the method of mathematical model operation of temporary instability of reaction found two types of oscillations of concentration of intermediate (harmonic and relaxation) characterized significantly by the differing times With increasing frequency and amplitude of low-frequency sonic waves (up to some critical value), we observed the disappearance of trimers and concomitant cessation of the reaction. Model operation of process showed a possibility of speed control of reaction at external lowfrequency acoustic influence.
