摘要：
The C-13 NMR techniques were selected to investigate the ion speciation in both DEAB and IPAB solvents. Calibration equations were established to quantify the exact ion concentration of free amines and protonated amines at different absorption times. The results show that the NMR method can be used to obtain both qualitative and quantitative information of the amine-CO2-H2O system. It is also the first time to monitor the components in the new solvent (IPAB) and establish its VLE model. (C) 2014 The Authors. Published by Elsevier Ltd.
