| Abstract: | A method for determination of the molecular weight distribution, which shows the internal quality of AEO products, of nonionic surfactants of dodecyl polyoxyethylene ether(AEO) was studied. AEO sample was pretreated by trimethyl silanization and analyzed by gas chromatography on OV-17 stationary phase. Identification and quantification were carried out based on standard sample and reference. The result was satisfactory to show the molecular weight distribution of AEO products. |
