液一液平衡에서 添加劑의 影響에 관한 硏究 = Study on the Effect of Additive Agents in Liquid-Liquid Equilibrium

다국어 초록 (Multilingual Abstract)

Binodal curves for solvent(1)-NaCl salt solution(2)-n-propyl alcohol(3) were measured to predict salts effect on ternary solvent(1)-water(2)-n-propyl alcohol(3) without NaCl salt at 25℃, Tie lines were determined from these bimodal curves, and consistency for these data was tested by correlating with Eisen-Joffe equation.
NaCl salt solutions were prepared for 5％, 15％, weight percent respectively. It was assumed that quaternany liquid-liquid equilibria with salt were converted to ternary liquid-liquid equilibria without salt if salt were excluded. The bimodal curves with NaCl salt were compared to bimodal curve without NaCl salt.
The parameters in the NRTL model and the calculated values of tie line were predicted. Quaternary distribution curves were determined for each salt concentration and salts effect on ternary system were examined.
