Solid-liquid equilibria of the following nine systems have been measured using Differential Scanning Calorimetry ( DSC )： Octanedioic acid ( 1 ) + 3-methylpentanedioic acid ( 2 )、Octanedioic acid ( 1 ) + 2,2-dimethylbutanedioic acid ( 2 )、Octanedioic acid ( 1 ) + 2,3-dimethylbutanedioic acid ( 2 )、Nonanedioic acid ( 1 ) + 3-methylpentanedioic acid ( 2 )、Nonanedioic acid ( 1 ) + 2,2-dimethylbutanedioic acid ( 2 )、Nonanedioic acid ( 1 ) + 2,3-dimethylbutanedioic acid ( 2 ) 、 Nonanedioic acid ( 1 ) + Octanedioic acid ( 2 )、Decanedioic acid ( 1 ) + 3-methylpentanedioic acid ( 2 )、Decanedioic acid ( 1 ) + 2,2-dimethylbutanedioic acid ( 2 ). This nine group of experimental data were compared with the results calculated from the Wilson and the NRTL model,and describe the experimental data of the graphics.
The study can supply the data of solid-liquid equilibrium for developing in thermodynamics thesis and providing basis reference data for industry segregation process.
