摘要
In this paper, the process of aspirin synthesis was studied by using on-line Raman spectroscopy. Wavelet analysis has been applied to remove the fluorescent background from the Raman spectra, and the variation of components concentration was determined with Multi-wavelength Linear Regression Method. The on-line Raman spectroscopy provided direct information about the variation of components concentration on the reaction time in the synthesis process.
