이산화탄소와 Anisole, Methyl anisole 이성질체와의 고압 이성분계 상평형
High Pressure Binary Phase Equilibria of Anisole, Methylanisole Isomers with Carbon Dioxide
초록
상온 상압에서 액상으로 존재하는 방향족 화합물중 anisole과 anisole에 methyl기를 ortho, meta, para 위치에 갖는 2-methylanisole, 3-methylanisole 및 4-methylanisole을 대상으로 이산화탄소의 각각 이성분계를 구성한계에 대해 상태방정식으로 Peng-Robinson(P-R)식과 perturbed-anisotropic-chain theory(PACT) 식을 이용, 평형상수인 K-factor를 이론적으로 구해 실험치와 비교 검토하여 본 계에 적용되는 이들 상태방정식의 특성을 고찰하였다.
Anisole and methyl anisole isomers which containing methyl functional group on anisole at the ortho, meta, para position were chosen as one of the aromatic hydrocarbons and carbon dioxide was chosen as the other component. K-factors obtained by experiment were compared with predictions from the perturb-ed-anisotropic-chain theory(PACT)and the Peng-Robinson(P-R) equation of state. The characteristics of Peng-Robinson(P-R) equation of state and perturbed-anisotropic-chain theory(PACT) which are applied on these systems were investigated.
