Abstract: PURPOSE: A method for preparing phenolate ionic liquid used as a carbon dioxide absorbent is provided to improve carbon dioxide absorbing ability and speed and to lower production cost. CONSTITUTION: A method for preparing phenolate ionic liquid is prepared by synthesizing an imidazolium cation and a phenolate anion. The imidazolium cation is (bmim)(1-butyl-3-methylimidazolium), (emim)(1-ethyl-3-methyimidazolium), or (hmim)(1-hexyl-3-methyimidazolium). A method for preparing the phenolate ionic liquid comprises: a step of mixing (imidazolium cation)Cl and Na-phenolate with methanol and stirring; and a step of removing NaCl and unreacted materials. [Reference numerals] (AA) Process of drying [imidazolium-based cation]Cl and Na-phenolate which are starting substances; (BB) Process of mixing and stirring methanol into each of two starting substances; (CC) Process of mixing and synthesizing two starting substances; (DD) Process of removing impurities; (EE) Solvent removing step; (FF) Washing step; (GG) Filtering step; (HH) Column filtering step

Abstract: PURPOSE: A manufacturing method of phenolate based ionic liquid, a product, and a separation method of carbon dioxide using thereof are provided to improve absorption of carbon dioxide, absorbing rate, and a playability and lower unit price. CONSTITUTION: A manufacturing method of phenolate based ionic liquid is processed by synthesizing imidazolium based cation and phenolate negative ion. The imidazolium based cation is (bmim)1-butyl-3-methylimidazolium, (emim)1-ethyl-3-methyimidazolium, or (hmim)1-hexyl-3-methyimidazolium. A phenolate based ionic liquid manufacturing method comprises the next steps: stirring after respectively mixing imidazolium based cation Cl and Na-phenolate with methanol solvent; synthesizing by stirring after mixing imidazolium based cation Cl which is mixed with methanol solvent with Na-phenolate; and refining process which eliminates materials which did not react and NaCl which is by-products of processed solution.
