Chemical kinetics of carbon dioxide with glycidyl methacrylate using immobilized tributylamine supported on poly(styrene-co-vinylbenzyl chloride) as a catalyst

Abstract

A soluble copolymer-supported catalyst containing pendant tributylammonium chloride was synthesized by the radical copolymerization of p-chloromethylated styrene followed by the addition reaction of the resulting copolymer with tributylamine. The absorption rate of carbon dioxide was measured from the absorption experiment into glycidyl methacrylate (GMA) solutions containing the catalyst in a semi-batch stirred tank with a plane gas–liquid interface at 0.1013 MPa. The reaction rate constants of the reaction between carbon dioxide and GMA were obtained by the analysis of the mass transfer mechanism accompanied by chemical reactions based on the film theory.Solvents such as toluene, N-methyl-2-pirrolidinone, and dimethyl sulfoxide influenced the reaction rate constants. Furthermore, this catalyst was compared to the monomeric tetrabutyl-ammonium chloride under the same reaction conditions.
