新型季铵型阳离子表面活性剂的合成及性能

Synthesis and Properties of a New Quaternary Ammonium Cationic Surfactant

以环氧大豆油为基本原料合成了一种季铵型阳离子表面活性剂,通过红外光谱和核磁共振氢谱对其结构进行了表征,并对其表面张力和临界胶束浓度进行了测定.

A new quaternary ammonium cationic surfactant was synthesized from epoxidised soybean oil and tertiary amine. The structure was confirmed by IR,~1H-NMR spectra and nitrogen content determination. Surface tension and critical micelle concentration of the product were also determined .
