Features of the kinetics of chemical reactions in a nanostructured liquid

Influence of Low-Frequency Sonolysis on the Stability of Reactions Involving Associates

“…In this work, we modeled the influence of low-frequency sonolysis on the stability of intermediates in the А + В → С reactions in associated liquids [2], by using the reaction of alcohol A and isocyanate B yielding urethane С as an example [1] with the formation of associates of reactant A, namely, dimer A 2 and trimer A 3 .…”

“…When studying the kinetics of liquid-phase reactions, the dependence of the rate constants on the concentration of the reagent, the extreme nature of the Arrhenius dependence of the rate constant on temperature were found [1] [2]. These kinetic anomalies are not described by the kinetics of a homogeneous medium.…”

“…These kinetic anomalies are not described by the kinetics of a homogeneous medium. The character of these anomalies is most strictly explained by the concept of the structural organization of the liquid during the formation of associates due to intermolecular interactions [2] [3] [4]. Theoretical and experimental data show that the association of molecules affects the reactivity of the molecules that form the associates [3] [4] [5] [6].…”

“…Previously, we have proposed [2] [3] [4] that some anomalies in the kinetics of bimolecular liquid-phase reactions can be explained by the formation of the associates of starting reagents. Earlier, the effect of sonolysis on the reaction kinetics in liquids was explored mostly for high-frequency acoustic waves [7] [8].…”

Influence of acoustic vibrations on the kinetics of liquid-phase chemical reactions involving associates

“…The action of acoustic wave with frequency v can be described by taking into account the stretching (σ) developed in the system according to the following expression for rate constants k(v) -i responsible for decomposition of associates: 1,5…”
