초록

본 연구에서는 물과 이산화탄소의 상호 용해력을 높이기 위한 방법의 하나로, 계면활성제를 이용하여 물과 이산화탄소의 마이크로에멀션 형성하는 조건을 관찰하였다. 물과 이산화탄소의 마이크로에멀션을 형성시키기 위하여 계면활성제2,2,3,3,3-Pentafluoro-1-propanol를 첨가하였다. 초임계 이산화탄소에 물과 계면활성제인 2,2,3,3,3-Pentafluoro-1-propanol 일정량을 첨가하여 이에 따른 마이크로에멀션의 구름점(cloud point) 변화와 경향을 살펴보았다. 계면활성제+이산화탄소 계의 경우 상전이 조건은 313.2 ~ 353.2 K 온도범위에서 8.35 ~ 12.69 MPa이였으며, 물+계면활성제+이산화탄소 계의 경우 온도범위 318.2 ~ 338.2 K에서 7.83 ~ 17.28 MPa에 이르는 압력 범위에서 구름점를 보였다.

In this study, microemulsion formation of water and carbon dioxide was investigated by using surfactant as one of the methods for increasing the mutual solubility between water and carbon dioxide. The surfactant 2,2,3,3,3-Pentafluoro-1-propanol was added to form a microemulsion of water and carbon dioxide. The cloud point change and trend of micro emulsion were investigated by adding water and a certain amount of surfactant, 2,2,3,3,3-Pentafluoro-1-propanol to supercritical carbon dioxide. In the case of surfactant + carbon dioxide system, it was 8.35 ~ 12.69 MPa in temperature range of 313.2 ~ 353.2 K. In the case of water + surfactant + carbon dioxide system, the temperature ranged from 318.2 ~ 338.2 K to pressure range 7.83 ~ 17.28 MPa.

Keywords:Water;Carbon dioxide;2,2,3,3,3-pentafluoro-1-propanol;High pressure phase equilibrium
