摘要： PURPOSE: An ionic liquid-based sulfur dioxide absorbing agent is provided to maintain the initial absorbing capability of the agent after the repetition of absorbing operations and desorption operations. CONSTITUTION: An ionic liquid-based sulfur dioxide absorbing agent includes ionic liquid and is represented by chemical formula 1. In the chemical formula 1, the R1 to R3 are respectively C1 to C8 alkyl group. The n is the integer of 1 to 8. The ionic liquid is selected from a group including 1-triethylene glycol monomethyl ether-3-methylimidazolium methansulfonate, 1-ethylene glycol monomethyl ether-3-methylimidazolium methansulfonate, 1-diethylene glycol monomethyl ether-3-methylimidazolium methansulfonate, 1-tetraethyleneglycol monomethylether-3-methylimidazolium methansulfonate, 1-hexaethylene glycol monomethyl-3-methylimidazolium methansulfonate, 1-octaethylene glycol monomethyl-3-methylimidazolium methansulfonate, and the mixture of the same.
