非离子Gemini表面活性剂的合成进展

双子（Gemini）表面活性剂是近年来迅速发展的一类新型表面活性剂，它是指分子中具有双亲水基和双亲油基的由一个间隔基团连接的表面活性剂，与传统表面活性剂相比，Gemini表面活性剂具有许多优异性能。相对而言，近年来非离子Gemini表面活性剂研究远较阴离子和阳离子的Gemini表面活性剂研究少。本文对非离子Gemini表面活性剂的研究现状进行了概述，以期对非离子Gemini类表面活性剂的研究与应用开发有所裨益。

The Synthesis Progress of Nonionic Gemini Surfactants

New classes of Gemini surfactants, two hydrophobic tails and two cationic head groups linked by spacer group i. e nonionic gemini surfactants, have emerged recently. Nowadays, different types of nonionic geminis were synthe-sized. In comparison with corresponding single chain surfactants, these surfactants were more efficient in lowering surface tension and have much lower cmc. Study of nonionic gemini surfactants were fewer than other gemini surfactants. The synthesis of nonionic gemini surfactants was reviewed, which was dedicated for promotion of the industrialization of the novel gemini surfactants.
