Reaction kinetics of the reaction between carbon dioxide and glycidyl methacrylate using tetraoctylammonium chloride as catalyst

Abstract

Carbon dioxide was absorbed in an organic solutions of glycidyl methacrylate (GMA) in a semi-batch stirred tank with a plane gas-liquid interface at 101.3 kPa to obtain the absorption rate of carbon dioxide, from which the reaction kinetics of the reaction between carbon dioxide and GMA as studied using tetraoctylammonium chloride as catalyst. The reaction rate constants were estimated from the mass transfer mechanism accompanied by the pseudo-first-order reaction with respect to the concentration of carbon dioxide. An empirical correlation formula between the reaction rate constants and the solubility parameters of solvents such as toluene, N-methyl-2-pyrrolidinone, and dimethyl sulfoxide is presented.

Absorption of carbon dioxide into glycidyl methacrylate solution with quaternary onium salts

“…Park et al [11][12][13][14][15][16][17] used tetrabutylammonium bromide [11], Aliquat 336 [12], tetraoctylammonium chloride [13], immobilized tetraoctylammonium chloride [14], immobilized tetrabutylammonium chloride [15], immobilized tetrahexylammonium bromide [16], immobilized tetraethylammonium chloride [17] as a catalyst to obtain the reaction kinetics of the reaction between CO 2 and glycidyl methacrylate (GMA) using the measured rate of CO 2 absorption. They presented the pseudo-first-order reaction method based on the reaction mechanism [4] with two steps to obtain the elementary reaction rate constants.…”
