Abstract

Supercritical fluid of carbon dioxide was used to investigate the effects of its temperature and density on the distribuion coefficients of fatty-acid esters composing fish oil. The distribution coefficient of fatty acid ester was greatly different from each other according to the temperature and density of the supercritical fluid. The possibility of separation of a certain fatty acid from the mixture of fatty acids was tested. The density of the supercritical fluid showing the great differences ofthe distribution coefficients among the fatty acid esters ranged from 0.3 g/mL to 0.4 g/mL. The retrograde condensation took place at high densities of the supercritical fluid.

초임계 유체 이산화탄소를 이용하여 그 온도와 밀도가 물고기 기름의 구성성분인 각종 지방산 에스터의 분배계수에 미치는 영향을 규명하였다. 각 지방산 에스터의 분배계수는 초임계 유체의 온도와 밀도에 따라서 상당한 차이를 나타내어 이산화탄소유체에 의한 지방산의 초임계 유체 추출분리 가능성을 확인할 수 있었다. 각 지방산의 분배계수 차이가 크게 나타나는 초임계 유체의 밀도는 0.3 g/mL 내지 0.4 /mL사이의 범위에 분포되어 있었다. 또한 각 지방산은 모두 초임계 유체의 밀도가 낮은 쪽보다 높은 쪽에서 온도에 따른 역행응축현상을 나타내었다.
