초록

두 초임계 시스템 CO₂-anisole, CO₂-tetralin의 상거동에 Peng-Robinson식을 적용하였다. 두 시스템에 대한 상평형의 계산치를 문헌상의 실험치에 접근시킴으로써 Peng-Robinson식 중의 매개변수값을 계산할 때 혼합물인 경우 이용하는 혼합규칙 중의 경험적 변수를 구하였다. 시스템의 온도의 변화에 따른 이들 경험적 변수의 경향을 추적하였다. 경험적 변수는 온도의 변화에 따라 선형적으로 변화하였다.

Peng-Robinson equation was applied to two supercritical systems of CO₂-anisole and CO₂-tetralin. For the two supercritical systems calculated phase equilibrium data were fitted to experimental data in the references. In the data fitting processes, values of mixture parameters of the mixing rule, which were used in the Peng-Robinson equation, were obtained. Trends of the mixture parameters of the mixing rule, which change with temperature of the system, were studied. Mixture parameters changed linearly with temperature.
