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 4):
The absorbent according to  claim 1 , wherein the organic solvent has an amide bond.
