A study of structure–activity relationships of commercial tertiary amines for post-combustion CO2 capture

•Ethyl group is beneficial for tertiary amines of CO2 absorption.•The existence of side carbon chain may promote the activity of tertiary amine.•Hydroxyl group reduces the equilibrium CO2 solubility, k2 and pKa.•Heterocyclic structure decrease the equilibrium CO2 solubility, k2 and pKa.•Hydroxyl gro...
