Abstract

The process of conversion of 20-25% solutions of calcium chloride obtained by decomposition of phosphorites of Central Kizikumes with sodium chlorate at 50, 75, 100 and 125 ° C with evaporation and without evaporation of conversion solutions has been studied. The process activation energies, the order and the rate constant of the conversion reaction as well as kinetic values of the reagent consumption are determined depending on temperature, time and carrying conditions of processes. The order of the conversion process of calcium chloride with sodium chlorate equals one. It is confirmed by the fact that the conversion rate constant calculated on the basis of experimental data remains practically constant for each temperature. Also, the linear dependence of lg (C0-Cτ) on τ also indicates the first order of the conversion process of calcium chloride with sodium chlorate. The rate constant of conversion increases with a rise in temperature. Its dependence on temperature obeys Arrhenius law. To establish values of the conversion rate constant for different temperatures, the constants (К0) for 20 and 25% solutions of calcium chloride have been calculated by Arrhenius equation and the dependence equation of lg K on 1 / T has been derived. It is confirmed by the linear graphical dependence of lg K on 1 / T. The expediency of carrying out the process of conversion with evaporation at a temperature of 100 ° C is established.
