聚硅氧烷季铵盐的合成及应用研究进展

Progress on Preparation and Application of Polysiloxane Quaternary Ammonium Salts

阐述了聚硅氧烷季铵盐的4种合成方法:氨基硅烷(油)与季铵化试剂的季铵化反应法、卤烃基硅烷与叔胺的取代反应法、含氢硅油(烷)与含活性基团的不饱和化合物的硅氢加成及季铵化反应法、甲基硅油与氨基硅烷、季铵盐的平衡反应法,介绍了其在织物整理、日化产品、农药、污水处理等方面的应用,并对其发展前景进行了展望。

Four synthetic methods for preparations of polysiloxane quaternary ammonium salts were sum- marized, i.e. quaternization reaction of amino silane （amino silicone） with quaternary ammonium reagent, substituted reaction of halogen alkyl silane with tertiary amine, hydrosilylation and quaternization reaction of the hydrogen silicone oil with unsaturated compounds containing active group, and the equilibrium polymeriza- tion or condensation reaction of methyl silicone oil and quaternary ammonium salt. The application of the pol- ysiloxane quaternary ammonium salts were introduced in the fabric finishing, daily chemical products, pesti- cides, sewage treatment and other applications. In the end, the development trends of polysiloxane quaternary ammonium salt were proposed.
