新型双阳离子季铵盐表面活性剂用作纸张杀菌抑菌剂

Application of Novel Gemini Quaternary Ammonium Salt as Paper Bacteriostatic Agent

在一定的环境下,长时间存放的纸张容易滋生细菌,可能会对使用者身体健康造成无法弥补的影响,为此,开发一种广谱高效的纸张杀菌抑菌剂具有重要的意义。以十二烷基二甲基胺和环氧氯丙烷为反应原料制备了一种新型双阳离子季铵盐表面活性剂,使用傅立叶变换红外光谱和元素分析仪确定产物的结构,使用抑菌圈实验法测试所制备化合物对纸张中大肠杆菌和金黄色葡萄球菌的杀菌抑菌性能。

In certain circumstances, the paper stored for a long times was easy to breed bacteria, that would damage the health of users. ＂lherefore, the development of a broad spectrum bactericidal agent for papers has important significance. N,N-Dimethyl dodecylamine and epichlorohydrin as reaction raw materials were used to synthesize a novel gemini quaternary ammonium salt surfactant in traditional method. FT-IR and Elemental Analyzer were used to determine the structure of the synthesized gemini quaternary ammonium salt. And then, bacteriostatic ring experiments were used to test the bacteriostatic properties of the compound to escherichia coli and staphylococcus aureus.
