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

The kinetics and mechanism of liquid-phase reactions were investigated in the presence of periodic mechanical action. This is the first stage of a larger project that will include mathematical modeling of basic kinetic schemes that take associate creation into account. In the case of a multistage reaction, multiple quasi stationary states and reagent concentration oscillations are possible.

The method of mathematical model operation of temporary instability of reaction was used to find two forms of oscillations of intermediate concentration (harmonic and relaxation), which were distinguished by their different periods. We observed the disappearance of trimers and the subsequent cessation of the reaction as the frequency and amplitude of low-frequency sonic waves increased (up to a critical value). The model operation of the process revealed the possibility of controlling the reaction speed in the presence of external lowfrequency acoustic impact.
