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.

methanoic acid：甲酸
該名稱來自于拉丁文中的表示醋的詞"acetum". 無水的乙酸在略低于室溫的溫度下(16.7℃),能夠轉(zhuǎn)化為一種具有腐蝕性的冰狀晶體,故常稱無水醋酸為冰醋酸. ① 蟻酸(formic acid) = 甲酸(methanoic acid)② 羊油酸(caproic acid) = 己酸(hexanoic acid)
