摘要
With α-octylpyridinium,α-dodeylpyridinium and 1,6-dibromohexane as raw materials,a new dissymmetric gemini surfactant was prepared.The structure of this compound was identified by qualitative experiments and spectral means.At the same time,surface activity of dissymmetric gemini surfactant was compared with corresponding symmetric gemini surfactant.The results show that dissymmetric gemini surfactant has lower CMC than corresponding symmetric gemini surfactant,and has higher efficiency to lower water surface intension.
