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。

The synthetic technologies of three hindered amine light stabilizers were established, the reason for the insoluble side products formed in the production of polymerized hindered amine light stabilizers were studied, and a series of novel hindered amine light stabilizers with antibacterial properties were designed and synthesized in this present paper.1. Based on the investigation of the transesterification between dimethyl sebacate and 1,2,2,6,6-pentamethyl-4-piperinol, the synthetic technologies of Tinuvin292 and Tinuvin 765 were established. The two kinds of hindered amine light stabilizers were obtained in the yield of 93.3% and 92.4% respectively and qualified as the advanced level of the kindred overseas products.2. The synthetic technology of Tinuvin123 was studied and established.

本文研究建立了三个受阻胺类光稳定剂的合成工艺，探索了聚合型受阻胺类光稳定剂生产过程中不溶性副产物产生的原因，并设计、合成了一系列具有抑菌活性的新型受阻胺类光稳定剂。1、在研究癸二酸二甲酯与1，2，2，6，6-五甲基哌啶醇的酯交换反应的基础上，建立了受阻胺类光稳定剂Tinuvin292、Tinuvin765的合成工艺，分别以93.3%和92.4%的收率得到了光稳定剂Tinuvin292、Tinuvin765，所得产品质量达到了国外同类产品的水平。2、研究建立了受阻胺类光稳定剂Tinuvin123的合成工艺。

The results show that methyl group strengthens the electrostatic attractions, but reduces the H-bonds effect, while benzyl group can make both electrostatic and H-bond effects strong. The theoretical results are identical with the results of the collectors flotation tests. Collecting ability of the quaternary amine salts is better than that of dodecylamine and dodecyl bimethyl amine. The quaternary amine salt containing benzyl group performs best, and it is little affected by pH value. Substitution of N-containing polar group in amine collectors can impact the aluminosulicate minerals flotation.

研究结果表明：甲基的取代可增强阳离子的静电作用能力，同时，削弱它与矿物表面之间的氢键作用；苄基的取代不仅增强药剂的静电效应，而且增加氢键的结合能力；理论分析结果与浮选试验结果一致，季铵盐的浮选能力较伯胺与叔胺的强，连有苄基的季铵盐对铝硅酸盐矿物的捕收能力最强，且受pH值影响小。
