Abstract:
The ionic liquid (IL) of 1,1,3,3-tetramethylguanidinum trifluoroacetate, which was synthesized by reacting 1,1,3,3-tetramethylguanidine (TMG) and trifluoroacetic acid, was used as a catalyst of the reaction between carbon dioxide and glycidyl methacrylate (GMA). The initial absorption rate of carbon dioxide into GMA solutions containing IL was measured in a semi-batch stirred tank with a plane gas-liquid interface at 101.3 kPa to obtain the reaction kinetics. The reaction rate constants of the reaction between carbon dioxide and GMA were evaluated from analysis of the mass transfer mechanism accompanied by the elementary reactions based on the film theory. Solvents such as toluene, N-methyl-2-pirrolidinone and dimethyl sulfoxide affected the reaction rate constants.Keywords: IONIC LIQUID; GAS ABSORPTION; CARBON DIOXIDE; GLYCIDYL METHACRYLATE
