초록

회분 병류 5단 평형추출에 의해 4종류의 질소고리화합물[indole(In), quinoline(Q), iso-quinoline(iQ), quinaldine(Qu)], 3종류의 2환 방향족화합물[1-methylnaphthalene(1MN), 2-methylnaphthalene(2MN), dimethyl naphthalene(DMN)], biphenyl과 phenyl ether로 구성된 모델 혼합물로부터 In의 분리를 검토했다. 본 연구의 원료로서 사용된 모델 혼합물은 콜타르 유분(유출온도범위: 240∼265 ℃)을 구성하고 있는 성분 및 조성을 고려하여 작성했다. 추출용매로서는 Formamide 수용액을 사용했다. 4단 평형추출을 통해 In을 99% 이상 회수할 수 있었다. 5단 평형추출을 통해 얻어진 DMN을 기준성분으로한 In의 선택도는 63∼118의 범위를 나타냈다. 본 연구를 통해 얻어진 실험적 결과와 이전의 연구결과를 이용하여 콜타르 중에 함유된 In의 분리 및 회수공정을 검토했다.

The separation of indole from a model mixture comprising four kinds of nitrogen heterocyclic compounds [indole (In), quinoline (Q), iso-quinoline (iQ), quinaldine (Qu)], three kinds of bicyclic aromatic compounds [1-methylnaphthalene (1MN), 2-methylnaphthalene (2MN), dimethylnaphthalene (DMN)], biphenyl (Bp) and phenyl ether (Pe) was examined by batch cocurrent 4 stages equilibrium extraction. The model mixture used as a raw material in this work was prepared according to the components and compositions contained in coal tar fraction (the temperature ranges of fraction: 240∼265 ℃). An aqueous solution of formamide was used as a solvent. Indole was recovered more than 99% through 4 stages of the equilibrium extraction. The range of selectivity of indole in reference to DMN obtained through the 5 stages equilibrium extraction was found to be 63∼118. The process for separation and recovery of indole contained in coal tar was studied by using the experimental results obtained from this work and the previous work.
