Three N‐lauroyl aromatic amino acid surfactants, namely, sodium N‐lauroyl phenylalaninate (SLP), sodium N‐lauroyl tyrosinate, and sodium N‐lauroyl tryptophanate (SLTr), with aromatic group structures were synthesized via methyl ester method. Mass spectrometry, Fourier transform infrared spectroscopy, and nuclear magnetic resonance were applied for the structural representation of products. A comparative study of the three surfactants in terms of surface, foam, and emulsifying properties and decontamination performance was conducted. Results demonstrated that aromatic structure significantly influenced the properties of the three surfactants. SLTr had the best surface performance and foam property, whereas SLP had the best emulsifying property. All three surfactants exhibited strong decontamination effects on protein‐soiled swatches.

三种N-月桂酰芳族氨基酸表面活性剂的合成与性能比较研究

合成了三种具有芳香族基团结构的N-月桂酰芳族氨基酸表面活性剂，即N-月桂酰苯丙氨酸钠（SLP），N-月桂酰酪氨酸钠和N-月桂酰色氨酸钠（SLTr）。甲酯法。质谱，傅里叶变换红外光谱和核磁共振被用于产品的结构表示。对三种表面活性剂的表面，泡沫，乳化性能和去污性能进行了比较研究。结果表明，芳族结构显着影响三种表面活性剂的性能。SLTr具有最佳的表面性能和发泡性能，而SLP具有最佳的乳化性能。所有三种表面活性剂均对蛋白污染的样品表现出较强的去污效果。
