A stopped-flow apparatus with conductivity detection was used. The reaction was modeled by means of a modified termolecular reaction mechanism which resulted in a second-order rate constant, and activation energies were calculated for a defined temperature range. Quantum chemical calculations at the B3LYP/6-31G(d) level also produced the activation energy of this reaction system which strongly supports the experimental findings.eninfo:eu-repo/semantics/closedAccessCO2-binding organic liquidDesorberless CO2 captureGuanidineTermolecular reactionArticleQ3404737744WOS:000397575600014
