The subject of the present invention is to provide a method for producing a silica gel supporting a derivatizing agent for a carbonyl compound that hardly collects carbonyl compounds during production thereof, and a silica gel supporting a derivatizing agent for a carbonyl compound produced by said production method, in order to lower a blank value in measurement of carbonyl compounds. The present invention also relates to a method for producing a silica gel supporting a derivatizing agent for a carbonyl compound characterized by bringing an acid-supported silica gel into contact with an organic solvent containing the derivatizing agent for a carbonyl compound, a silica gel filler supporting a derivatizing agent for a carbonyl compound comprising the silica gel supporting the derivatizing agent for a carbonyl compound produced by the above production method, a method for producing a silica gel supporting a derivatizing agent for a carbonyl compound characterized by treating in advance a silica gel having a cation-exchange group with the derivatizing agent for a carbonyl compound and then bringing it into contact with an organic solvent containing the derivatizing agent for a carbonyl compound, and the like.
本发明的目的是提供一种在生产过程中几乎不收集羰基化合物的支持羰基化合物衍生剂的硅胶的生产方法,以及通过上述生产方法生产的支持羰基化合物衍生剂的硅胶,以降低羰基化合物测量中的空白值。本发明还涉及一种生产支持羰基化合物衍生剂的硅胶的方法,其特征在于使酸支持的硅胶与含有羰基化合物衍生剂的有机溶剂接触,支持羰基化合物衍生剂的硅胶填料包括通过上述生产方法生产的支持羰基化合物衍生剂的硅胶、一种支持羰基化合物衍生剂的硅胶的生产方法,其特征在于预先用羰基化合物衍生剂处理具有阳离子交换基团的硅胶,然后使其与含有羰基化合物衍生剂的有机溶剂接触,等等。
