摘要: ABSTRACTA series of novel alkoxy nonionic biosurfactants were synthesized by ring-opening reaction methoxy poly(ethylene glycols) and alkylene oxide. The chemical structures these confirmed Fourier-transform infrared spectroscopy (FTIR) 1HNMR spectra. surface tensions in the aqueous solutions determined using a tensionmeter. results showed that critical micelle concentrations decreased with increase hydrophobic chain. However, due to effect intermolecular hydrogen bonding, increased increasing chain lower than those conventional biosurfactants. Meanwhile, effects electrolytes on tension slight. Due excellent activity, could have great potential cleansing, oil recovery, drug delivery.
