- Abstract
The number of observations that demonstrate a significant effect of the size of droplets on the kinetics of chemical processes has increased with the expansion of the scope of applications of spray technology. The equations linking the concentrations of reagents, the volume of droplets, the initial composition of a solution, the composition of the gas medium, and the speed of processes are formulated within the framework of formal chemical kinetics. Using second order reactions (coupling, exchange, condensation, polymerization, and polycondensation reactions) as examples, it is shown that size kinetic effects occur when chemical processes are accompanied by changes in the droplet sizes in equilibrium with the gas medium. The results of computer simulation of condensation and polycondensation reactions are given, which reproduce size effects. Kinetic curves obtained by simulation of the polycondensation process are compared with experimental data.
