摘　　要：以氢氧化钠为催化剂,使用正丁醇与环氧烷烃制备聚醚,并以该聚醚为原料通过一步法依次制备聚醚胺和聚醚胺烯酐。通过红外光谱(IR)、核磁共振(NMR)和质谱(MS)等检测手段,确定目标产物结构。考察了不同剂量聚醚胺和聚醚胺烯酐在不同温度下对燃油黏度的影响,研究了聚醚胺和聚醚胺烯酐在燃油中的清净性能。研究表明,聚醚胺烯酐比聚醚胺有更好的清净性能。In this study,sodium hydroxide was used as catalyst to prepare polyethers using n-butanol and alkylene oxide,and polyetheramines and polyetheramine alkene anhydrides were prepared using the polyethers as raw materials.The structure of the target products was determined by infrared spectroscopy(IR),nuclear magnetic resonance(NMR)and mass spectrometry(MS).The influence of different doses of polyether amine and polyether amine anhydride on fuel viscosity at different temperatures was investigated.The detergency performance of polyetheramine and polyetheramine alkene anhydride in fuel was investigated.It was found that polyetheramine alkene anhydride has better detergency performance than polyetheramine.
