ABSORBENTS FOR SEPARATION OF ACIDIC GAS

摘要

PURPOSE: An absorbent for separating acidic gas is provided to reduce energy consumption when the absorbent is reproduced by easily stripping carbon dioxide, and to rapidly remove the carbon dioxide with good absorbing power. CONSTITUTION: An absorbent for separating acidic gas include a compound represented by a chemical formula 1, a second compound represented by a chemical formula 2, and a compound selected from groups of a chemical formula 3 ~ 7. In the chemical formula 1, a is an integer of 1 ~ 4. R1 is an alkyl group of carbon number 1 ~ 6. R2 is methyl. In the chemical formula 2, b is an integer of 0 ~ 3. R3 is hydrogen, or an alkyl group of carbon number 1 ~ 6.
