    • The invention aims at providing a process for the production of silica gels carrying derivatization agents for carbonyl compounds which little suffers from the capture of carbonyl compounds during the production and thus makes it possible to give silica gel products exhibiting lowered blank values in the determination of carbonyl compounds; and silica gels carrying derivatization agents for carbonyl compounds which are produced by the process. The invention relates to a process for the production of silica gels carrying derivatization agents for carbonyl compounds, characterized by bringing a silica gel carrying an acid into contact with an organic solvent containing a derivatization agent for carbonyl compounds; packings consisting of silica gels carrying derivatization agents for carbonyl compounds, produced by the process; a process for the production of silica gels carrying derivatization agents for carbonyl compounds, characterized by pre-treating a silica gel bearing cation-exchange groups with a derivatization agent for carbonyl compounds and then bringing the resulting silica gel into contact with an organic solvent containing a derivatization agent for carbonyl compounds; and so on.
    • 本发明的目的在于提供一种生产含有羰基化合物的衍生化剂的二氧化硅凝胶的方法,该方法在生产过程中几乎不能捕获羰基化合物,因此可以得到在测定羰基中表现出降低的空白值的硅胶产物 化合物; 和含有通过该方法生产的用于羰基化合物的衍生化剂的硅胶。 本发明涉及一种生产含有羰基化合物的衍生化剂的硅胶的制备方法,其特征在于使含有酸的硅胶与含有羰基化合物的衍生化剂的有机溶剂接触; 由通过该方法制备的携带羰基化合物的衍生化剂的硅胶组成的填料; 用于生产携带羰基化合物的衍生化剂的硅胶的方法,其特征在于用羰基化合物的衍生化试剂预先处理带有阳离子交换基团的硅胶,然后使得到的硅胶与含有 羰基化合物的衍生剂; 等等。
