摘要: In this paper, kinetics and mechanism of the reaction between CO 2 piperazine (PZ) or n-methyl (NMP) in aqueous alcoholic solutions were investigated using direct stopped-flow technique under a range temperatures (278, 288 298 K). The results show that reactions follow single termolecular rate PZ (2669(278K), 11335(288K), 18042(298K) m3/kmol⋅s) is significantly higher than commonly employed amines, such as monoethanolamine (MEA). Our strongly suggest derivatives can be used promoters for capture by sterically hindered amine solutions.
