新型酯基有机硅季铵盐的设计合成、表征及其性能研究
Study on the Synthesis,Characterization and Properties of New Ester-based Silicone Quaternary Ammonium Salts
摘要
Abstract
The L16(45)orthogonal tests were designed to investigate the effect of molar ratio of reactants, reaction time,microwave power,catalyst and solvent dosage etc.On the reaction between lauric acid methyl two ethanolamine single(double)of ester and(γ-chloropropyl)trimethoxysilane,and the opti-mum conditions of quaternization were obtained.The molar ratio of γ-(chloropropyl)trimethoxysilane to N-methyldiethanolamine is 1.5:1,the catalyst(KI)is 20% of the moles of the N-methyldiethano-lamine,and the amount of the solvent N,N-dimethylformamide is 50% of the total reactants mass,mi-crowave power 810 W,refluxing reaction for 70 min.The results showed that the yield of ester-based or-ganic silicon quaternary ammonium salt reached 74.5% by bromophenol blue method.And the cotton cloth was impregnated with the aqueous solution of the synthesized product,then dehydrated and dried. The antibacteria and resistance to washing performances of the treated cotton cloth were determined by nutrient broth dilution method and nutrient agar method.The results showed that the treated sample had a bactericidal ratio more than 99% although after 8 times washing when the sample was processed of by the aqueous solution of the product at 200 μg /mL,dehydrated and dried at 120 ℃ for 15 min,indicating that the prepared organosilicone quaternary ammonium salt has a good antibacteria and sustained-release properties.关键词
