Abstract: | The intermediate and final products of the reactions of magnesium with diphenylantimony and diphenylbismuth chlorides were identified, and the formal kinetic relationships of the process were elucidated. The apparent equilibrium constants, enthalpies, and entropies of adsorption of the reagents on the metal surface, and also the rate constants and activation energies of the reactions in dimethylformamide-p-xylene mixture were determined. Probable schemes of magnesium oxidation with the organobismuth and organoantimony chlorides were considered. |
