An ionic liquid (IDBE-CP-MS41), imidazole-immobilized on chloropropyl-functionalized MCM-41, was synthesized by a grafting technique through a co-condensation method and used as a catalyst in the reaction of carbon dioxide with glycidyl methacrylate (GMA). CO2 was absorbed into the heterogeneous system of the GMA solution and dispersed with solid particles of the catalyst in a batch stirred tank with a plane gas-liquid interface at 101.3 kPa. The absorption of CO2 was analyzed using the mass transfer mechanism accompanied by chemical reactions based on the film theory. The proposed model fits the measured data of the enhancement factor to obtain the reaction rate constants. Solvents such as N, N-dimethylacetamide, N-methyl-2-pyrrolidinone, and dimethyl sulfoxide influenced reaction rate constants. |
