| titleOfInvention | 4, 5-imidazole dicarboxylic acid modified organic-silica gel hybrid monolithic column and application |
| abstract | The invention discloses a 4, 5-imidazole dicarboxylic acid modified organic-silica gel hybrid monolithic column, which can be used for separation and analysis of polar compounds, and the preparation method comprises the following steps: introducing a mixed solution of tetramethoxysilane and chloropropyltrimethoxysilane in a proper proportion into a pretreated capillary, heating for reaction to prepare a chloropropyl-silica gel hybrid monolithic column bed, then flushing excessive ammonia water solution of 4, 5-imidazole dicarboxylic acid into the chloropropyl-silica gel hybrid monolithic column bed, and heating to obtain the catalyst. The invention develops a novel functionalized organic-silica gel hybrid monolithic column by bonding water-soluble organic functional monomers, and the hybrid monolithic column can be applied to separation and analysis of different types of polar compounds in a water-rich or reversed-phase chromatographic mode. |
