| Abstract: | Fourier transform infrared spectrometer was employed to scan the gasoline and dimethyl carbonate,and the characteristic absorption peak of dimethyl carbonate was obtained.Based on the Lambert-Bill principle,quantitative analysis of dimethyl carbonate was obtained.Results showed that the Fourier infrared spectroscopy method allowed for the accurate determination of dimethyl carbonate in the gasoline.The method had fast analysis speed,good repeatability and low cost analysis. |
