摘　　要： The isothermal mutual solubility and phase relation of MgSO 4-Li 2SO 4-C 2H 5OH-H 2O system at 25 ℃ have been investigated by using a homemade micro-equilibrium and sampling apparatus. The demixing phenomenon of the system′s at below room temperature was observed. The precise demixing composition and composition of double-saturated point of the system have been determined. A unique effect, namely additive property between MgSO 4 and Li 2SO 4 has been observed and explained in terms of "pseudo-ternary system" concept. An empirical formula has been worked out to correlate the mutual solubility.
