合成并测定了Ｎ，Ｎ’－烷撑双脂肪酰胺系列化合物的红外吸收光谱和电 子轰击源质谱，对其质谱断裂途径进行总结，并用环状离子解释了谱图中主 要碎片离子的来源。结果表明，Ｎ，Ｎ－烷撑双脂肪酞胺具有仲酰胺的红外吸 收光谱特征；当烷撑和脂肪酸链长不同时，具有相似质谱断裂形式。
Synthesis and determination of N, N’-alkylene bis-fatty amide series of infrared absorption spectra and electron impact ionization mass spectrometry, mass spectrometry fracture pathways were summarized, and the use of ring ions explain the source of the main fragment ions in the spectrum. The results showed that N, N-alkylene bis-aliphatic-phthalocyanine had the characteristic of infrared absorption spectrum of secondary amide. When the chain lengths of alkylene oxide and fatty acid were different, it had similar mass spectrum.
