Ti-MCM-22 촉매를 이용한 프로필렌 에폭시화반응
Propylene Epoxidation Using Ti-MCM-22 Catalyst
티타늄 함유 제올라이트 촉매 Ti-MCM-22를 이용하여 과산화수소를 산화제로 한 프로필렌 에폭시화반응을 수행하였으며, 반응 온도와 압력, 촉매량, 한계 반응물인 과산화수소의 농도, 산화프로필렌의 첨가, 용매 및 촉매 재생 효과를 조사하였다. Acetonitrile 용매 하에서 반응 실험을 수행한 결과, 99% 이상의 H2O2 전화율과 100%에 근접하는 산화프로필렌 선택도를 보였다.
Propylene epoxidation by H2O2 (30% aqueous) as oxidant was studied in a semi-batch reactor using Ti-MCM-22 catalyst: Effects of reaction temperature, pressure, catalyst loading, solvent, and H2O2 concentration on H2O2 conversion (limiting reagent) were investigated. Product inhibition by propylene oxide was confirmed. Ti-MCM-22 maintained virtually the same catalytic performance over the 5 repeated cycles.
