(JP2017104775) PROBLEM TO BE SOLVED: Compared to conventional aqueous amine solution is high in absorption near room temperature, at high temperatures and excellent in ease of de-oiler, low evaporation loss, low specific heat, the heat of reaction is reduced, and recovering the carbon dioxide absorbing solution of carbon dioxide per reduced energy required for regeneration of the carbon dioxide absorbing solution capable of providing. SOLUTION: A carbon dioxide absorbent liquid, the chemical absorbent with nitrogen - hydrogen bonding amine and carbon dioxide, comprising a hydrogen bond accepting misicle solvent, the solvent is a hydrogen bond accepting property, phosphate anions, phosphoric acid, phosphonic acid or phosphonic acid ester ionic liquid, or a carbonyl group or an electron-attractive group has a phosphinyl groups, carbonyl groups are carbon atoms 2 one nitrogen atom is bonded to, at least on the phosphorus atom arkylester phosphinyl 1 bonded to one nitrogen atom in the amide compound.
