(KR101508710) Disclosed is a method for synthesizing an ionic liquid for dissolving coal. The method for synthesizing an ionic liquid for dissolving coal disclosed according to an embodiment of the present invention comprises the steps of: (S100) dissolving a first precursor in methylene chloride at an appropriate ratio in order to be cooled; (S200) injecting tosyl chloride and potassium hydroxide in the solution; (S300) agitating the solution at room temperature after a particular period of time in order to be changed into a white suspension, washing a filtrate several times with distilled water in a filtering process, removing the moisture of an organic layer, and performing vacuum concentration; (S400) synthesizing a second precursor which is a white solid through a plurality of column chromatography techniques; (S500) injecting methylimidazole in the second precursor in order to be mixed into a solvent which is also a reagent; (S600) performing a reflux process at an appropriate temperature; and (S700) obtaining a plurality of final ionic liquids by washing layer-separated oil with anhydrous ether dozens of times.
