双子咪唑啉季铵盐的合成及其乳化性能研究

Synthesis and Performance of Quaternary Ammonium Bis-imidazoline as Emulsifier

摘要:

本文首先以二丁胺和环氧氯丙烷为原料合成N-丁基-N,N-二（3-氯-2-羟丙基）丁烷-1-铵盐；然后利用其与长链烷基咪唑啉进行季铵化反应合成双子咪唑啉季铵盐，并通过FTIR和HNMR验证了目标产物的结构；最后利用合成的双子咪唑啉季铵盐和秦皇岛AH-70重交道路沥青制备乳化沥青，进行了双子咪唑啉季铵盐的乳化性能考察。结果表明，在皂液pH值为5、沥青温度为135℃、皂液温度为55℃、乳化剂加量为1.5％的条件下制备的乳化沥青达到交通部JTG F40-2004的质量要求。

Abstract:

Firstly, Gemini imidazoline quaternary ammonium was prepared with butyl amine and epoxy chloropropane and long chain imidazoline. And the structure of the synthesized product was characterized by FTIR and HNMR. Then, emulsified asphalt was made by the Gemini imidazoline quaternary ammonium and Qin huangdao AH-70 asphalt and the preparation conditions of emulsified asphalt was investigated. In addition, the economic benefit of Gemini imidazoline quaternary ammonium was analyzed. The results show that the optimal conditions were as follows: pH value was 5.0, the asphalt temperature was 135℃, the soap liquid temperature was 55℃, the mass ratio of water and oil was 6:4, and emulsifier dosage was 1.5%.
