초록
여러 가지 고체산 촉매를 이용하여 2-naphthol과 에탄올의 에테르화 반응을 연구하였다. 본 연구에서 촉매는 CNS, CNSWS, SCMS, MCF, SBA-15와 이 촉매에 sulfonic acid를 붙인 CNS-SO3H, CNSWS-SO3H, SCMS-SO3H, MCFSO3H, SBA-15-SO3H를 사용하였다. 반응온도 180 ℃, LHSV=1 h-1, 에탄올/2-naphthol의 몰 비 20인 조건으로 고정층 반응기에서 반응하여 각 촉매에서 2-naphthol의 전환율과 2-naphthyl ethyl ether의 선택도를 측정하였다. 2-naphthol의 전환율과 2-naphthyl ethyl ether의 선택도는 carbon 계열의 고체산 촉매에서 보다 silica 계열의 고체산 촉매에서 더 높게 나타났다. silica 계열의 고체산 촉매에서 2-naphthol의 전환율은 70~90%, 2-naphthyl ethyl ether의 선택도는 90%이상으로 나타났다. 촉매의 특성을 관찰하기 위해 XRD, SEM, TEM, NH3-TPD를 수행하였다.
The etherification of 2-naphthol with ethanol has been carried out over various solid acid catalysts. CNS, CNSWS, SCMS, MCF, and SBA-15 with and without sulfonic acid were used in this study as solid acid catalysts. The conversion of 2-naphthol and the selectivity of 2-naphthyl ethyl ether were obtained at reaction temperature = 180 ℃, LHSV = 1 h-1, ethanol/2-naphthol molar ratio = 20 using a fixed-bed down flow reactor. The conversion of 2-naphthol and the selectivity of 2-naphthyl ethyl ether over silica group catalysts were higher than them over carbon group catalysts. The conversion of 2-naphthol was 70-90% and the selectivity of 2-naphthyl ethyl ether was more than 90% over silica group solid acid catalysts. It was performed XRD, SEM, TEM, and NH3-TPD to characterize solid acid catalysts.
