Determination of m-Cresol and p-Cresol in Industrial Cresols by Raman Spectrometer

Abstract:

Adopting raman spectrometer to conduct qualitative and quantitative analysis of m-cresol and p-cresol, selecting the respective character peak of bencycloquidium after deformation vibration (m-cresol at 732 cm-1 and p-cresol at 841 cm-1), via experiment and calculations, the relative raman cross section of m-cresol and p-cresol can be concluded:(∂σ/∂Ω)_732cm^-1/(∂σ/∂Ω)_1000cm^-1 is 0.74 (height-fitting of the peak), and 0.61 (area-fitting of the peak). This method samples simply and rapidly, and has a short testing time, whose quantitative analysis result of m-/p-cresol is consistent with that of GC analysis.
