One route was that the amino-groups on the silica gel were transformed to tertiary amines by Eschweiler-clarke reaction that amine-groups react with formaldehyde and methanoic acid to prepare tertiary amines; the silica gel intermediates with tertiary amine groups reacted with chorohydrocarbons to prepare insoluble silica gel quaternary ammonium salt bactericides. Another route was that the amino-groups on the silica gel reacted with excessive chlorohexadecane; the preparing intermediates were quaternized with iodomethane to obtain insoluble silica gel quaternary ammonium salt bactericides.
一条路线是根据埃施韦勒-克拉克(Eschweiler-clarke)胺甲基化反应，进行胺基叔胺化反应，制成带有叔胺官能团的硅胶中间体，此中间体上的叔胺与卤代烷反应生成杀菌活性官能团季铵盐，制成硅胶类水不溶性季铵盐杀菌剂；另一条路线是带有胺反应活性中心的硅胶与过量正氯代十六烷反应，得到的中间体再用碘甲烷季铵化，得到最终产品——水不溶性季铵盐杀菌剂。

methanoic acid：甲酸
该名称来自于拉丁文中的表示醋的词"acetum". 无水的乙酸在略低于室温的温度下(16.7℃),能够转化为一种具有腐蚀性的冰状晶体,故常称无水醋酸为冰醋酸. ① 蚁酸(formic acid) = 甲酸(methanoic acid)② 羊油酸(caproic acid) = 己酸(hexanoic acid)
