In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.
本文通过一系列的实验,合成了两个系列的Gemini型表面活性剂,即双烷撑双季铵盐表面活性剂m-s-m·2Br和双烷撑双季铵盐表面活性剂-s-·2Br,用红外光谱对其结构进行了表征,并且对影响合成双烷撑双季铵盐表面活性剂反应的因素进行了讨论,找出了合成双乙撑双季铵盐表面活性剂m-2-m·2Br的最佳条件:溴代烷与四甲基乙二胺的摩尔比为3.0:1.0,以乙醇作溶剂,在回流温度80℃下反应48小时;合成双烷撑双季铵盐表面活性剂12-s-12·2Br的最佳条件:十二叔胺与1,3-二溴丙烷(1,4-二溴丁烷)摩尔比为2.2:1.0,以乙醇作溶剂,在恒温80℃下回流反应48小时。

The bioassay results showed that the quaternary ammonium salt had a good intihtion against typical microorganisms such as heterotrophic bacteria,ammonifying bacteria,denitrifying bacteria and nitrosation bacteria with its inhibition rate was above 90%. Inhibition of the quaternary ammonium salt to fungi and sulfate reducting bacteria was above 85% after 30 min. Inhibition of the quaternary ammonium salt to black mold was about 84% after 30 min,and the to algae was totally inhibited after 24 h.
