中文摘要：

分别以两种叔胺中间体与γ-氯丙基甲基硅油通过季铵化反应，制得有机硅季铵盐N，N-二甲基-N-辛基氨丙基聚硅氧烷氯化铵（POASC）和N，N-二甲基-N-十三氟辛基氨丙基聚硅氧烷氯化铵（PFASC）。探讨了反应溶剂、温度和时间对季铵化产率的影响，确定最优工艺为：以DMF为溶剂，100℃下反应24h，季铵化产率可达88．2％。将合成的有机硅季铵盐应用于棉织物抗菌整理，通过XPS和SEM确定两种抗茵剂均已成功整理到棉织物表面。经有机硅季铵盐POASC和PFASC整理后的棉织物具有光滑、柔软的手感。抗菌试验表明：整理后的棉织物对大肠杆菌和金黄色葡萄球菌的抑菌率均有很大提高，其中经有机硅季铵盐PFASC整理后的棉织物对大肠杆菌的抑菌率达到99．21％，对金黄色葡萄球菌的抑茵率达到99．49％。

英文摘要：

This study prepares organosilicon quaternary ammonium salts N, N-dimethyl-N-POASC and N, N-dimethyl-N- PFASC respectively with two tertiary amine intermediates and γ-chloride propyl methyl silicone oil through quaternization reaction, discusses the influence of reactive solvent, temperature and time on quarternization yield and determines the optimal process, i.e. quarternization yield can achieve 88.2% under the condition of DMF solvent and 24-hour reaction at 100 ℃. It applies synthesized organosilicon quaternary ammonium salts to antibacterial finishing of cotton fabrics and determines through XPS and SEM that both antibacterial agents have been successfully finished on the surface of cotton fabrics. Cotton fabrics subject to finishing with organosilicon quaternary ammonium salts POASC and PFASC are smooth and soft. Antibacterial test shows that cotton fabrics after finishing have a greatly increased antibacterial rate against escherichia coli and staphylococcus aureus; the antibacterial rate of cotton fabrics subject to finishing with organosilicon quaternary ammonium salt PFASC against escherichia coli is 99.21% and that against staphylococcus aureus is 99.49%.
