Polycaprolactone, 디클로로메탄, 이산화탄소로 구성된 3성분계 고압 상거동 측정
High-Pressure Phase Behavior of Polycaprolactone, Carbon Dioxide, and Dichloromethane Ternary Mixture Systems
Polycaprolactone, Dichloromethane, 이산화탄소로 구성된 3성분계 고압 시스템의 상거동 측정 실험은 가변 부피 셀 장치를 이용해서 측정했다. 실험의 온도범위는 313.15 K에서 353.15 K, 압력은 약 300 bar까지 측정했으며 실험결과는 Polycaprolactone의 질량 분율이 1.0%, 2.0%, 3.0%일 때 온도와 이산화탄소/Dichloromethane의 질량 분율로 정리했다. 또한 실험 결과는 hybrid 상태방정식 (Peng-Robinson 상태방정식과 SAFT 상태방정식의 혼합형태) 을 이용하여 열역학적으로 검증하였으며, 혼합규칙은 반데르 발스의 단일 유체 혼합규칙을 사용했다. 이 다성분계 시스템에서 이원 상호 작용 파라미터 등, 각종 파라미터는 심플렉스 알고리즘을 통해 최적화했다.
The high-pressure phase behavior of a polycaprolactone (Mw=56,145 g/mol, polydispersity 1.2), dichloromethane, and carbon dioxide ternary system was measured using a variable-volume view cell. The experimental temperatures and pressures ranged from 313.15 K to 353.15 K and up to 300 bar as functions of the CO2/dichloromethane mass ratio and temperature, at poly(D-lactic acid) weight fractions of 1.0, 2.0, and 3.0%. The correlation results were obtained from the hybrid equation of state (Peng-Robinson equation of state + SAFT equation of state) for the CO2-polymer system using the van der Waals one-fluid mixing rule. The three binary interaction parameters were optimized by the simplex method algorithm.
