This experiment with methyl imidazole,1 bromodecane as raw materials, to take the route of synthesis of the imidazole surfactant , characterization of the melting point of the synthetic products, as well as surfactant. Key words： ionic liquid。 關鍵詞 ：離子液體；咪唑；表面活性 Abstract Ionic liquids as a new type of green material, nonvolatile, nonbustible, reusable, good thermal stability, and physicochemical properties tunable characteristics, and in fine anic synthesis, catalysis, electrochemistry, materials science, bioengineering and energy and other areas has been widely used. Existing most widely used ionic liquid alkyl methyl of imidazole salt, however, its design, polarity, polar weak anic performance of low defect limits its industrial progress further applications. Design and development of new, special features of ionic liquid materials to meet different needs and enrich the ionic liquid and basic chemical theory is of great significance. Imidazole surfactants are a new class of surfactant. For 1 alkyl 3 – methyl imidazolium bromide, when the alkyl chain length is shorter, it is at room temperature liquid, almost no vapor pressure, nonflammable, nonfire point, thermal stability and high chemical stability of the ionic liquid, and chemical separation, the field of anic synthesis, nanomaterials and solar cells, etc. are widely used. When its longer alkyl chain, similar to traditional cationic surfactants, and amphiphilic Imidazolium ionic liquid has been widely studied. Studies have shown that pared with traditional cationic surfactant alkyl trimethyl ammonium bromide, longchain ionic liquid has a higher surface activity. Thesis review and experiments in two parts： Summary of part of the system overview of the classification of the ionic liquid。 本實驗主要以 甲基咪唑 、 1溴代十二烷為原料 ，采取咪唑類表面活性 子液體的合成 路線 。研究表明，與傳統(tǒng)的陽離子表面活性劑 — 烷基三甲基溴化銨相比，這種長鏈咪唑離子液具有更高的表面活性。對于 1烷基 3甲基咪唑溴而言，當烷基鏈的長度較短時，它是 一 種在常溫下為液體、幾乎無蒸汽壓、無可燃性、無著火點、熱穩(wěn)定性和化學穩(wěn)定性高的離子液體，并在化學分離、有機合成 、納米材料和太陽能電池等領域得到了廣泛的應用。因此設計開發(fā)新型的、具有特殊功能的離子液體材料來滿足不同的需求并豐富離子液體基礎化學理論，具有重要意義。 本科畢業(yè)設 計（ 論 文） 題目 一種表面活性 離子液體的合成 學生姓名 陳亮 學 號 0804040541 教學院系 化學化工
