Abstract: The solubilities and refractive indexes of saturated solutions of the systems BaCl2-C6H12O6-H2O/(H2Oand CH3CH2OH) have been determined at 30 ℃, and the corresponding equilibrium phase diagram and refractive index curves were constructed. The results indicated that the solubility curves and the refractive index curves of saturated solutions consist of three branches, corresponding to BaCl2·2H2O, BaCl2·2C6H12O6·2H2O and C6H12O6·H2Orespectively, in these systems. The ternary compound BaCl2·2C6H12O6·2H2Owhich has not been reported is congruently soluble in H2Oor in mixed solvent of H2Oand CH3CH2OH. With the increase of the amount of ethyl alcohol in mixed solvent, the solubilities of the BaCl2·2H2O, BaCl2·2C6H12O6·2H2Oand C6H12O6·H2Odecrease gradually.
