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。

Accordingly, we start the thesis from two small oil fields of Beipu and Laoyemiao in Nanpu depression. Firstly, we analyze regional geology background of the area and find that its structure evolvement can be divided into three greatest stages: the formation and evolution of pre-tertiary basement, the lower-tertiary fault basin and the upper-tertiary depression basin.
因此本论文从南堡凹陷北堡和老爷庙两个小型油田入手，首先分析了研究区的区域地质背景，明确了其构造演化分为三大阶段：即前第三纪基底的形成与演化、早第三纪断陷盆地的形成与演化、晚第三纪坳陷盆地的形成与演化。
