| Abstract: | Three kinds of model compounds of polyether surfactants were separated and refined through a method of silica gel column chromatography from different industrial products, and their qualitative analysis was carried out by infrared spectroscopy,and their structures and EO(PO) distributions were determined by 1H NMR. Taking the three kinds of model compounds of polyether surfactants as the basis,a calculation method for alkyl group chain length and EO(PO) distributions of the polyether surfactants were proposed. |
