초록

유통형의 평형추출장치를 제작하고 초임계 상태의 이산화탄소중에 phenol과 그 염화물인 p-chlorophenol, 2,4-dichlorophenol, 2,6-dichlorophenol, 2,4,6-trichlorophenol의 용해도를 309.2K, 318.2K, 333.2K의 일정온도와 8-20MPa의 압력범위에서 측정하였다. 용해도의 측정값과 Peng- Robinson의 상태방정식을 사용하여 얻은 추산값은 잘 일치하며 계의 온도가 용질의 용융점 근방 또는 약간 높은 온도에서도 용융액상에 대한 이산화탄소의 용해도를 무시한 기-고계 평형계산은 실험값을 잘 표현할 수 있었다. 상태방정식중의 용질의 a,b를 parameter로 취급하여 측정한 용해도를 가장 잘 표현하는 parameter를 구하였고 동일한 2성분계에서 얻은 a, b는 온도에 크게 영향받지 않았다. 용해도로부터 계산한 enhancement factor의 대수값과 유체의 밀도는 직선적인 관계로 표시될 수 있으며 그 관계는 온도에 약간의 영향을 받고 있음을 확인하였다.

The solubilities of phenol, p-chlorophenol, 2,4-dichlorophenol, 2,6-dichlorophenol and 2,4,6-trich-lorophenol in carbon dioxide were measured under the supercritical conditions of pressure range between 8 and 20MPa, and 309.2K, 318.2K and 333.2K, using the flow-type apparatus that was newly manufactured. The solubilities were good agreement with the equilibrium data predicted by using Peng-Robinson equation of state, although temperature of a and b in the equation of state were obtained by regression method utilizing the experimental solubilties and they and little affected by the temperature for a binary system. The enhancement factor obtained from the solubility data was linearly related in semi-log plot, and the relations were affected by the temperature of a binary system.
