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.

He wore, when he walked out, a purple silk hat and carried a gold-headed cane. Over his eyes he wore great spectacles with gold rims, not because his eyes were bad but because the spectacles made him look wise, and so distinguished and gorgeous was his appearance that all the Yips were very proud of him.

他出门的时候，常戴着一顶紫色的绸礼帽，拄着一个纯金头的手杖；他在眼睛上架了一付镶金边的大眼镜，那倒不是因为他的视力不好，而是戴上眼镜看上去能使他显得更聪明一些，他的外表就显得更高贵典雅，以致于所有的耶普人都为他感到自豪。
