分别采用1,3二溴丙烷和环氧氯丙烷与十二烷基二甲基叔胺季铵化,得到阳离子型Gemini-I(二溴化-(N,N,N’,N’-四甲基)-N,N’-二(十二烷基)-丙二胺)和Gemini-II(二溴化-(N,N,N’,N’-四甲基)-N,N’-二(十二烷基)-2-羟基-丙二胺),将其分别与I2单质复合,获得两种新型有机/无机复合杀菌剂.Gemini及其复合物的有效成份分别为87.4%、94.8%和8.6%、10.1%;1HNMR谱、13CNMR谱检测确定了Gemini的结构,Raman光谱检测初步确定了复合体系中有机/无机间弱结合结构.好氧菌及厌氧菌杀灭性检测结果表明,浓度为30mg/L时,Gemini对大肠杆菌的杀灭率分别为92.8%和98.5%;Geminis/I2对硫酸盐还原菌(SRB)的杀灭率分别为51.4%和63.9%,复合后灭菌性均较Gemini有明显提高.
Were quaternized with 1,3 dibromopropane and epichlorohydrin, respectively, and dodecyldimethyl tertiary amine to give the cationic Gemini-I (dibromo- (N, N, N ’, N’- Methyl) -N, N’-didodecyl-propylenediamine) and Gemini-II (dibromo- (N, N, N ’, N’-tetramethyl) -N, N’ (Dodecyl) -2-hydroxy-propanediamine), respectively, to obtain two new organic / inorganic compound bactericides.The active ingredients of Gemini and its complex were 87.4% 94.8% and 8.6%, 10.1% respectively. The structure of Gemini was confirmed by 1HNMR and 13CNMR spectroscopy. The weak organic / inorganic bond structure in the composite system was determined by Raman spectroscopy. The killing results of aerobic and anaerobic bacteria The results showed that the killing rates of Gemini to Escherichia coli were 92.8% and 98.5% at the concentration of 30mg / L, and the kill rates of Geminis / I2 to SRB were 51.4% and 63.9% Sterilization than Gemini significantly improved.
