摘要：

Ethylolamides of animal (beef and mutton) fats have been synthesized and modified with H3PO4. The identity of these products was confirmed by IR and NMR spectroscopy. The physical properties of the synthesized surfactants including interfacial tension and critical micelle concentration (CMC) were studied. From these measurements, the maximum surface excess concentration and the minimum area per molecule at the kerosene solution/water interface, the surface pressure at the CMC, and the standard thermodynamic parameters of adsorption and micellization were calculated. Ethylolamides and ethylolamide phosphates were obtained and tested as petroleum-collecting and petroleum-dispersing reagents. Some correlations between these parameters of the ethylol units and their ability to collect thin petroleum films from the water surface were revealed.
