Abstract

Using lead loadings in the form of single plates with different weights and physical surfaces, as well as sets of different numbers of plates and approximately the same total mass during its oxidation in organic phases containing molecular iodine and hydrogen peroxide simultaneously and only hydrogen peroxide as an oxidizer, a simulation of the possible consequences of rolling lead particles with bulk shapes into thin plates under the influence of mechanical factors in the course of oxidative processes has been carried out. It was established that single plates under the selected conditions were consumed in accordance with zero-order macrokinetics and velocities which increased with increasing the plate mass and decreasing its physical surface. The same trend persists in sets of plates: the more plates in the set while maintaining the total mass, the worse the process proceeds. At the same time, each set corresponds to its own type of the macrokinetic curve of lead consumption in the range from auto-accelerated development with a transition to the stationary or wave mode to auto-delayed development with an exit to a very slow, stationary mode close to zero order. Consequently, the rolling of particles of bulk forms into plates during the process automatically leads to a slowdown in the passing, which cannot be eliminated by external influence.
