We found minimal fluctuations in strength or region in the 2800 cm −1 spectral area (Fig. 7), which is in keeping with the FTIR spectrum of DEG published by Obeidat et al. . In Diethylene glycol's FTIR spectrum, at the 1234–1456 cm −1 wavelength range, IR absorption WebJul 1, 2012 · In order to find out the catalytic mechanism active while using PEG/NaOH, the solubilisation products were characterized in more detail. Fig. 2 compares FTIR spectra of the epoxy resin before and after its solubilisation. After solubilisation the characteristic peak of ester at 1730 cm −1 almost disappears, while the strength of the –OH band increases, …
