摘      要：CO_(2)capture with a low energy consumption is of important application significance for reducing CO_(2)*** phase-change absorbent developed in recent years shows its potential for low-energy CO_(2)*** unclear phase-splitting rule hinders the efficient development of CO_(2)phase-change *** predict phase-splitting behaviors of mono/poly-amine-organic solvent-water system with various concentrations,a quasi-activity coefficient was developed based on Debye&Mc Aulay equation and some Density function theory *** models based on Debye&Mc Aulay equation were developed with different ion radius,descriptors or poly-amine-CO_(2)*** phase-splitting boundary was drawn on the model with the best *** quasi-activity coefficient would provide guidance for the phase-splitting systems development,especially for polyamines.
