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