However, the surplus residual chlorine can affect people's taste and smell, destroy the quality of water. Moreover, in the process of disinfection, chlorine can react with organic matter and produce a series of hydrochloric ether such as chloroform, bromoform, bromodichloromethane, chlorodibromomethane and so on, these matters can cause to some extent cancer to human body.
但是，水中过量的余氯会影响水的口感和气味，破坏水的品质；此外，在消毒过程中，氯与水中残余的有机物产生化学作用，生成一系列氯代烃如三氯甲烷、溴仿、溴二氯甲烷、氯二溴甲烷等，这些物质会对人体产生一定程度的致癌作用；对于以自然水源作为生活用水来源的城市必然要对水加氯消毒后才可使用。

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。

According to the Box-Benhnken design principle,the method of response surface method with 3 factors and 3 levels was used. The factors influencing the technological parameters were determined by means of regression analysis. Response surfaces were finally graphed with the yield as the response value. The synthesis conditions were optimized as follows:reaction reagent was NBS,stoichiometric proportion between NBS and anhydrovinblastine was 1.07; the dosage of TFA was 22 mL/L; reaction temperature was －68 ℃ and duration was 90 min.
在单因素实验基础上，根据Box-Benhnken实验设计原理，采用三因素三水平的响应面分析法，研究了各个因素及其交互作用后，得到了合成7′-Br-脱水长春碱的最佳工艺条件：以二氯甲烷为溶剂，采用NBS为溴代剂，其用量与底物的物质的量比为1.07∶1，TFA的加入量22 mL/L，在－68 ℃下反应90 min，终止反应后，得到卤代产物。
