pseudo–first‐order reaction kinetics of different aqueous‐based single and blended amines over the temperature range of 298.15‐313.15 K using stopped‐flow techniques. The single amines include one primary amine (monoethanolamine, MEA), two secondary amines (diethanolamine, DEA and 2‐ethyl(amino)ethanol, 2EAE), four tertiary amines (N‐methyldiethanolamine, MDEA, 1‐dimethylamino‐2‐propanol, 1DMA2P, 3‐dimethylamino‐1‐propanol
本研究使用停止流技术建立了在298.15-313.15 K温度范围内不同水基单胺和共混胺的直接拟一级反应动力学。单胺包括一种伯胺(单乙醇胺,MEA),两种仲胺(二乙醇胺,DEA和2-乙基(氨基)乙醇,2EAE),四种叔胺(N-甲基二乙醇胺,MDEA,1-二甲基氨基-2-丙醇, 1DMA2P,3-二甲基氨基-1-丙醇,3DMA1P和2-二甲基氨基乙醇2DMAE),一种空间位阻胺(2-氨基-2-甲基-1-丙醇,AMP)和一种环状二胺(哌嗪,PZ)。使用的共混系统为MEA / PZ,DEA / PZ,MDEA / PZ,AMP / PZ,MEA / AMP,MDEA / 2EAE,1DMA2P / 2EAE,3DMA1P / 2EAE和2DMAE / 2EAE。
