Abstract

A study towards the kinetics of CO2 with several aqueous salts of amino acids was performed at a temperature of 298 K. Absorption rate experiments were carried out in the pseudo-first-order regime, enabling the determination of the kinetic rate constant from the flux. In a preliminary screening at a concentration of 0.5 moL-1 the potassium salts of 6-aminohexanoic acid, β-alanine, l-arginine, l-glutamic acid, dl-methionine, l-proline and sarcosine were investigated. Based on the results of this screening the aqueous potassium salts of sarcosine and proline were considered to be the most promising solvents. For these solvents, and the corresponding lithium solvents, the physical distribution coefficient of N2O was determined for various temperatures and concentrations. Subsequently for these same solvents the kinetics were more extensively studied at 298 K in which the concentration of the amino acid salts was varied between 0.5 and 3moL-1.
