Abstract:
A carbon dioxide absorbent of an embodiment includes a heterocyclic amine expressed by Formula (1), and the heterocyclic amine having a pKa of any one amino group included in a heterocyclic ring in Formula (1) in a range of 7.0 or more to 8.6 or less and an organic solvent having a boiling point of 150° C. or more at 1 atm. A total mass of the heterocyclic amine and the organic solvent is 70 mass % or more to 100 mass % or less of the carbon dioxide absorbent. Each of R 1  to R 4  in Formula (1) is H, oxygen double-bonded with carbon of the heterocyclic ring, CH 3 , OH, or an alkyl chain optionally including a functional group. X 1  in Formula (1) is H, CH 3 , CO, C(O)OC 2 H 5 , C(O)OC 3 H 7 , C(O)OCH(CH 3 ) 2 , C(O)OC(CH 3 ) 3 , C(O)OCH 3 , C(O)CH 3 , or C(O)C 2 H 5 .

Claim (Index 9):
The absorbent according to  claim 1 , wherein the absorbent is a carbon dioxide unabsorbed carbon dioxide absorbent, the carbon dioxide unabsorbed carbon dioxide absorbent is used in an apparatus of separating and recovering carbon dioxide, the apparatus including:\n an absorption tower configured to separate and recover carbon dioxide from gas containing carbon dioxide by contacting the gas containing carbon dioxide with the carbon dioxide unabsorbed carbon dioxide absorbent to allow carbon dioxide to be absorbed in the carbon dioxide unabsorbed carbon dioxide absorbent, and a carbon dioxide absorbed carbon dioxide absorbent is obtained; and a regeneration tower configured to regenerate the carbon dioxide absorbed carbon dioxide absorbent by desorbing carbon dioxide from the carbon dioxide absorbed carbon dioxide absorbent which has absorbed carbon dioxide.
