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.

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.
