metadata.name: dc.description.abstract
metadata.value: The article discusses the process of sublimation of chemically pure ammonium chloride crystals. Instrumental studies were conducted using synchronous thermal analysis, including thermogravimetry and differential scanning calorimetry, under non-isothermal conditions with three different heating rates (3, 5, and 10 В°C/min). The data obtained from the experiments were processed using the Friedman isoconversion method. Based on the assumption that the sublimation process consists of three successive stages that can be modeled by n-th order reaction kinetics, a kinetic model was developed to describe the change in sample mass over time. Statistical and nonlinear regression techniques were used to determine the kinetic triplets for each stage. The model was then applied to predict the progression of the sublimation process under various temperature regimes. The results of the work can be used both in an independent form and in the construction of complex models of chemical processes in which it is necessary to take into account the course of a competing process of sublimation of ammonium chloride.
