| Abstract: | Capillary (HP4890) gas chromatography method has been developed for the separation and determination of lower distribution alkyl alcohol polyoxyethylene ether(AEO).These AEO samples were separated on quartz capillary column. This experiment adopt the program rising temperture, FID detector. The components of AEO samples were identified by GC/MS. The free alkyl alcohol and ethoxymer distribution of polyoxyethylene of AEO sample were determined by normalization method. In comparing with previous methods, this method is simple, fast and more reproducible. |
