摘要
Abstract
Alkyl polyglycosides (APGs) with different carbon chains from C10 to C14 were synthesized and characterized with infrared spectroscopy. The influence of APG concentration and carbon chain length on the surface and interfacial properties were both studied. The results showed that the surface tension and diesel-water interfacial tension were gradually decreased with increasing the concentration of APG,while the capacity of foaming,foam stabiling and emulsifying were enhanced. On the other hand,with increasing carbon chain length,the critical micelle concentration (cmc) value of APG, surface tension,and diesel-water interfacial tension were decreased,while the capacity of foaming, foam stabiling and emulsifying were enhanced on the contrary. Because of their good surface and interfacial properties,APGs were applied to prepare emulsion as emulsifier. This work showed that the capacity of emulsifying was enhanced with increasing APGs concentration and carbon chain length. Furthermore,the micromorphology measurements demonstrated that the stability,droplets uniformity and fillibility of the emulsion stabilized by different APGs were superior to that stabilized by OP-10. Finally,this work showed that the stabilization time had little effect on the micromorphology of emulsion and C14APG was the most optimal surfactant among all the APGs studied.关键词
