초록

본 연구는 메탄올 추출에 의해 조제 메틸나프탈렌유(CMNO) 중에 함유된 인돌(IN)의 분리성능을 실험적으로 검토한 후, 이들 결과를 포름아미드 추출과 비교했다. 원료로서는 의약, 필수 아미노산, 향료의 중간원료로서 주목되고 있는 IN이 약 4.36% 함유된 CMNO를, 용매로서는 메탄올 수용액을 각각 사용했다. 용매에 함유된 물의 체적분율(yw,0)의 증가는 IN의 분배계수(mIN)와 수율(YIN)을 급격히 감소시켰으나, 역으로 2-메틸나프탈렌(2MNA)을 기준한 IN의 선택도 (𝛽IN,2MNA)는 증가시켰다. 초기 원료에 대한 용매의 체적분율(E0/R0)의 증가는 mIN, YIN과 𝛽IN,2MNA를 증가시켰다. 0.1 ≤ yw,0 ≤ 0.3의 범위에서, 메탄올 추출의 mIN와 YIN은 포름아미드 추출에 비해 약 1.9~5.9배, 1.8~3.6배 컸으나, 𝛽IN,2MNA는 역으로 포름아미드 추출이 메탄올 추출에 비해 4.6~8.2배 컸다.

This study experimentally examined the separation performance of indole (IN) contained in crude methyl naphthalene oil (CMNO) by methanol extraction and then compared these results with formamide extraction. CMNO containing about 4.36% IN, which is attracting attention as an intermediate raw material such as medicine, essential amino acids, and perfumes, was used as a raw material, and methanol aqueous solution was used as a solvent, respectively. The increase in the initial volume fraction of water in the solvent (yw,0) sharply decreased the distribution coefficient (mIN) and yield (YIN) of IN, but conversely increased the selectivity of IN in reference to 2-methylnaphthalene (2MNA). An increase in the initial volume ratio of solvent to feed (E0/R0) increased mIN, YIN, and 𝛽IN,2MNA. In the range of 0.1 ≤ yw,0 ≤ 0.3, mIN and YIN of methanol extraction were approximately 1.9~5.9 times and 1.8~3.6 times greater than those of formamide extraction, respectively, whereas 𝛽IN,2MNA of formamide extraction were 4.6~8.2 times greater than those of methanol extraction.
