Imidazole → HCID 131725032, compound

Temperature

45 °C

A flask fitted with a reflux condenser, magnetic stirrer, and temperature controller was charged with 225 mL deionized water and 70.0 g (1.0 moles) imidazole (C3H4N2). The resulting solution was heated to about 45° C. and 185.5 (3.0 moles) boric acid was added with stirring. The mixture was then heated to 90° C. and maintained with stirring for 1 h, cooled to 45° C., filtered, and washed with water. The resulting white powder was washed with about 100 mL deionized water and dried at 105° C. It was identified as imidazolium nonaborate by x-ray diffraction and titration analysis. Elemental analyses for the product are shown in Table 5, along with the theoretical analyses for imidazolium nonaborate, [C3H5N2]2O.3B2O3.2H2O.
