摘要
Abstract
The organic silicone quaternary ammonium salt with multi-heads was synthesized using hexamethylenetetramine andγ-chloropropyltrimethoxysilane as raw materials. The target product was characterized by FTIR and NMR. Furthermore,process optimization experiments was carried out. Reaction rate and yield were improved by microwave technology and reaction yield was up to 95.6%within 8 hours. In addition,the major performance of the target product was investigated,such as fusion point,surface tension,critical micelle concentration and bactericidal property. The product contained three quaternary ammonium groups per molecule on average. Fusion point of the above organosilicon quaternary ammonium salt ranged from 86.2 ℃ to 88.6 ℃.γCMC of the product was 46.30 mN/m. CMC was 0.19 g/L,and the bacteriostatic zone diameter for escherichia coli could be up to 27.4 cm.关键词
