摘要：
Heterogeneous equilibria in the manganese-carbamide-sulfuric acid-water quaternary system at 25°C are studied using the solubility method. The concentration boundaries are determined for crystallization of the initial solid components, eutectic compositions of the ternary systems, and binary compounds formed in the carbamide-sulfuric acid-water and carbamide-manganese sulfate-water systems, as well as for new compounds simultaneously containing carbamide, manganese sulfate, and sulfuric acid at a 1: 4: 1 and 1: 2: 1 ratios.
