|
摘要
以壬基酚、三乙烯四胺和甲醛为原料合成出一种新型阳离子沥青乳化剂2-三乙烯四胺基亚甲基-4-壬基苯酚。最佳合成条件为:反应时间5 h,反应温度95℃,甲醛与壬基酚的摩尔比2.8,三乙烯四胺与壬基酚的摩尔比1.0。在最佳工艺条件下反应的产率可达49.21%。利用红外光谱对产物结构进行了表征。利用在线红外光谱技术对该反应进行了追踪分析,检测到中间产物。基于以上试验数据,提出了合理的反应机理。该乳化剂对AH-90沥青具有很好的乳化能力。
A novel cationic type asphalt emulsifier of 2-triethylenetetramine methylene-4-nonylphenol was synthesized by the reaction of nonylphenol,triethylenetetramine and formaldehyde.The optimum reaction condition was obtained.The yield reached 49.21%in the optimum reaction condition of the feedstock mole ratio of formaldehyde to nonylphenol 2.8,feedstock mole ratio of triethylenetetramine to nonyl phenol1.0,reaction temperature 95 ℃,and reaction time 5 h.The structure of the emulsifier was identified by FTIR.The synthesis process was monitored by online FTIR technique.Based upon the experimental data,a reasonable reaction mechanism was proposed for the reaction.The emulsifier presented satisfactory emulsification to AH-90 asphalt.
