MCM41에 담지된 Imidazole 촉매에 의한 Glycidyl Methacrylate와 이산화탄소의 반응속도론
Reaction Kinetics of Carbon Dioxide and Glycidyl Methacrylate using a Ionic Liquid Catalyst of Imidazole Immobilized on MCM41
중간세공크기(mesopore)의 MCM41에 Imidazole을 담지시킨 CP-MS41 고체 입자의 촉매를 사용하여 GMA 용액에 CO2를 흡수시켜 CO2의 흡수기구로부터 GMA와 CO2의 반응속도론을 고찰하였다. 대기압에서 회분식 흡수조를 사용하여 임펠러의 교반속도, 50 rpm, 촉매, 2 g, 반응온도, 60, 70, 80 ℃, GMA의 농도, 0.1~3.0 kmol/m3, 용제, DMA, NMP, DMSO에서 측정한 CO2의 흡수속도와 경막설에 의한 물질수지식을 사용하여 반응속도상수를 구하였다.
Carbon dioxide was absorbed into GMA solution in a stirred flat cell using mesoporous catalyst Imidazole-CP-MS41, which was synthesized by CP-MCM41 with imidazole. Experiments were carried out at a batch-type absorber with different conditions, varying reaction temperature, concentration of GMA, solvent but maintaining 50 rpm of agitation speed and 2 g of catalyst. Absorption rate of CO2 was used to obtain the kinetics based on the film theory using zwitterion
mechanism with 2 elementary reaction and the kinetics were correlated with the solubility parameter of the solvents.
