【摘要】 以气相法白炭黑(FS)、偶联剂和叔胺为原料,合成了3种气相法白炭黑季铵盐衍生物(DQAFS),并用红外光谱对其结构进行了表征。防霉抗菌试验表明:用悬菌定量法,3种DQAFS对大肠杆菌(8099)和金黄色葡萄球菌(ATCC6538)的15min抑菌率都达到99.99%,而对采自蓝湿革的混合霉菌的抑制效果则有很大区别,定性试验结果表明,有的是完全抑制,有的几乎无作用。更多还原

【Abstract】 Three kinds of fumed silica derivatives modified with quaternary ammonium salts (DQAFS) were synthesised with fumed silica (FS), coupling agent and tertiary amine, and their structures were characterized by Fourier-transform infrared spectroscopy (FTIR). The results indicate that for Escherichia coli (8099) and Staphylococcus (ATCC6538), the inhibition rates of three kinds of DQAFS are all 99.99% exposed to the microorganism in 15 min. But for the mixing fungus from wet-blue leather, their inhibiting abilities are of great differences. Some of them show highly effective, while others almost have no inhibiting effects.更多还原
