一种新型表面活性剂的合成及应用

Synthesis and Application of A New Gemini Surfactants

介绍了通过五水四氯化锡、环氧氯丙烷、乙二醇等物质合成双子表面活性剂的方法,并采用了减压蒸馏、薄层层析、柱层析等提纯和分离方法,通过电导法测定新型助剂的CMC值;通过FD8(23)析因分析试验法确定了助剂的用量、温度、pH值对活性染料上染的最佳前处理条件。实验结果表明,合成的助剂不仅能够对不同棉用染料发生作用,而且很大程度上提高了活性染料对棉纤维的染色深度,显著降低无机盐和碱剂的用量。

A new type of gemini surfactants(TM) was synthesized from epichlorohydrin, ethanedioljauryl alcohol etc and then purified. Its CMC value is determined by conductivity method. The best pretreatment conditions beneficial to reactive dyeing are figured out by factor analysis.
