피리딘-물-용매의 三成分系에서 相平衡에 관한 硏究 = Study on the phase equilibria in ternary systems of pyridine-water-solvent

다국어 초록 (Multilingual Abstract)

The experimental binodal curves, tie lines, plait point, distribution coefficient, and selectivity were determined for the ternary systems of pyridine-water with eyclohexane, o-xylene, monochlorobenzene, n-butyl aeatate, aniline and ethyl acetate as solvent at 25℃ and also for the quarternary solvent-NaCl salt solution-pyridine systems at 25℃.
The NaCl salt solutions were prepared with aqueous solutiom of 5%, 10% and 15% NaCl salts respectively.
The experimental tie line data were correlated with the NRTL, UNIQUAC and modified UNIQUAC model, and the parameter and the calculated values of tie line were predicted. The effect of salt addition on liquid-liquid equilibria were also studied.
Thus, the following results were obtained for the utilization of the basic data in the design of extraction apparatus.
1. The experimental binodal curves and tie line data were determined for the ternary solvent-water-pyridine system and the quarternary solvent-NaCl salt solution-pyridine systems, and those experimental tie line data were used to test thermodynamic consistency.
2. The calculated tie line data were well agreed with the experimental tie line data within RMSD values as shown in the Table-8,10.
3. The plait point data were obtain using method of Trebal et al and presented in Table 12 and Table 13.
4. As the concentration of NaCl salt increased 10% and 15%, plait point disappeared, and solvent extraction was well done around plait point.
5. The solutropy phenomenon was occurred by using o-xylene monochlorobenzene, n-butyl acetate at solvent, but at the concentration of HaCl salt was 10%, 15%, the solutropy phenomena was disappeared.
6. When the concentration of NaCl salt increased, the distribution coefficient and selectivity increased and the effect of solvent was improved.
