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.

The approach of preparation method is that, first, blend yttria into hot aquafortis, add silicone grease chemical compound after reaction, cool it to form gel. Second, heat the gel for 1-48 hours to acquire solid fruitage. Third, igloss the fruitage in reducing gas for 1-48 hours. Forth, add anorg and then igloss it in reducing gas for 1-48 hours in the temperature between 800-1600 degree.
