摘　　要：丁氟螨酯是一种新型杀螨剂,具有高效、低残留的特点.本文对其红外吸收光谱(IR)、紫外吸收光谱(UV)、质谱(MS)及核磁共振(NMR)波谱(包括1H NMR、13C NMR、DEPT、1H-1H COSY、1H-13C HSQC、1H-13C HMBC)进行了测定,分析了其UV和IR谱图特征吸收峰对应的基团,并对其1H和13C NMR信号进行了归属,确证了丁氟螨酯的结构.该研究将为丁氟螨酯的其他相关研究提供参考.Cyflumetofen is a new type of acaricide with high efficiency and low residue.In this work,the compound was characterized by infrared absorption(IR),ultraviolet absorption(UV)and mass spectrometry,as well as nuclear magnetic resonance spectroscopy(1H NMR,13 C NMR,DEPT,1H-1H COSY,1H-13 C HSQC and 1H-13 C HMBC).The characteristic absorption peaks in the UV and IR spectra were discussed.The 1H and 13 C NMR signals of cyflumetofen were assigned,and the two-dimensional signals were used to elucidate its structure.
