The solid-liquid equilibrium data for a ternary system of 4-hydroxybenzaldehyde (3) + 3-bromo-4-hydroxybenzaldehyde (2) + 3,5-dibromo-4-hydroxybenzaldehyde (1) were determined with differential scanning calorimetry (D...The solid-liquid equilibrium data for a ternary system of 4-hydroxybenzaldehyde (3) + 3-bromo-4-hydroxybenzaldehyde (2) + 3,5-dibromo-4-hydroxybenzaldehyde (1) were determined with differential scanning calorimetry (DSC).The data were obtained through the method of determining the solid-liquid equilibrium data for the pseudo-binary solution.The solid-liquid equilibrium data of the ternary system showed that the mixture was a eutectic system with mole fractions xl=0.2445,x2=0.3883,x3 =0.3672,and Teu=338.5 K.The corresponding eutectic type phase diagram was also presented.The data were correlated by the Ott’s equation.With interaction parameters from binary systems,the Wilson equation was extended to correlate the solid-liquid equilibrium data of the ternary system and the root mean square deviation of temperature was only 0.97 K.It demonstrates that the Wilson equation predicts the solid-liquid equilibrium for the ternary system with fair accuracy.展开更多
