Abstract

The reaction between COS and various tertiary alkanolamines in aqueous solutions has been studied in an intensely stirred batch reactor. Experiments for TEA, DMMEA, and DEMEA were carried out at 303 K the reaction between COS and aqueous MDEA has been studied at temperaturm ranging from 293 to 323 K. A two-step reaction mechanism haa been proposed which describes all observed phenomena. This mechanism can be regarded as the base-catalyzed analogue of the reaction mechanism for the hydrolysis of COS. The proposed reaction mechanism was confirmed by absorption experiments into nonaqueous solutions of tertiary alkanolamines.
