| Abstract: | Fourier transform infrared spectrometer was employed to scan the gasoline and dimethoxymethane,ob- tained characteristic absorption peak of dimethoxymethane ; and based on the Lambert - Bill principle, quantitative a- nalysis of dimethoxymethane was obtained. Results showed that, the Fourier infrared spectroscopy method allowed for the accurate determination of dimethoxymethane in the gasoline. The method had fast analysis speed, good repeatabili- ty and low cost analysis. |
