Abstract
Official abstract text for this publication.
The present invention discloses a glucose gemini surfactant compound comprising a dodecyl glucose gemini surfactant and tetradecyltrimethylammonium chloride, or a tetradecyl glucose gemini surfactant and cetyl trimethylammonium bromide; the present invention also discloses a process for the preparation of the glucose gemini surfactant compounds. The glucose gemini surfactant compounds of the invention have the high activity characteristic of the gemini surfactant and is suitable for the separation and extraction of the detergents and the biofilm protein, and are novel non-toxic or low toxic and biodegradable glycosyl gemini surfactants. The preparation method of the compound surfactants is simple and easy to be industrialized.
