| titleOfInvention | Sulfur dioxide gas absorbent |
| abstract | The invention discloses a sulfur dioxide gas absorbent, which consists of an aqueous solution of an alcohol amine ionic liquid and a furoic acid type functional ionic liquid, wherein the mixed molar ratio of the alcohol amine ionic liquid and the furoic acid type functional ionic liquidThe ratio is 1: 5-10; furfuryl acid is used for replacing traditional carboxylic acid to synthesize bio-based anion functionalized ionic liquid, and the bio-based anion functionalized ionic liquid is compounded with alcohol amine ionic liquid to form a mixed absorbent, oxygen atoms on a furan ring in the furoic acid type functionalized ionic liquid and hydrogen atoms on amino groups in the alcohol amine ionic liquid form hydrogen bonds, SO that the residual hydrogen atoms in the amino groups become more active and can form hydrogen bonds with oxygen atoms in sulfur dioxide, the hydrogen bonds become more urgent, and the absorption of sulfur dioxide gas is better facilitated through the mixed synergistic effect of the alcohol amine type ionic liquid and the furoic acid type functionalized ionic liquid, and the SO provided by the invention 2 Absorbent pair SO 2 Has high absorption rate and selectivity, good regenerability and stability, and is beneficial to the recycling of the absorbent. |
