To a 500 ml-three neck flask, 49.8 g of isophthalic acid and 300 ml of acetone were added and stirred. Thereto, 33.1 g of 2-ethyl-4-methylimidazole dissolved separately with 60 ml of acetone was dropped by heating. After dropping, the resultant was heated at reflux for 3 hours, cooled, and then subjected to suction filtration. By performing vacuum drying, 79.2 of the clathrate complex of isophthalic acid/2-ethyl-4-methylimidazole (1:1) was obtained. The clathration of the obtained clathrate complex was confirmed by 1H-NMR, TG-DTA and XRD.
