The solubility data of the calcium acetate-magnesium acetate-water system at 298, 313, and 323 K were measured using the Schreinemaker’s wet residue method, the corresponding phase diagram for the system were constructed. The solid phase in the system at different temperatures was confirmed by the Schreinemaker’s wet residue method, which correspond to Mg(CH3COO)2·4H2O and Ca(CH3COO)2·2H2O. At the studied temperature, no double salt was formed. The crystalline region of Ca(CH3COO)2·2H2O is larger than that of Mg(CH3COO)2·4H2O. The solubility of Mg(CH3COO)2 increases with the increasing of the temperature, while the solubility of Ca(CH3COO)2 decreases with the increasing of the temperature.
