The comparative spectroscopic study of OilWPB, OilJFWPB and OilFFWPB with the help of Fourier Transform Infrared Spectroscopy (FTIR) and Gas Chromatography Mass Spectrometry (GC/MS), which explains the transformations of chemical compounds from one functional group to other respective oxidative functional groups and with the help of GC/MS analysis of OilWPB, OilJFWPB and OilFFWPB the components of the recovered oil samples were identified. It was also reported that by changing the natural fiber in reaction mixture the synthesized oxidative products were also changes. The existence of characteristic transmittance bands at 3618.46 cm-1, 3363.86 cm-1, 2191.13 cm-1, 1732.08 cm-1 & 912.33 cm-1 and 912.33 cm-1 & 883.40 cm-1, corresponds Alcohol, Primary amine, Nitrile, Carbonyls and Aromatics with mono substitution respectively and the reduction in intensities of the bands intensely confirms the transformations of =C-H, C=C, =CH2 functional group into the alcohols (ROH), primary amines(R2NH), nitriles (-C=N-), carbonyls (C=O and C-O) and mono substituted aromatic.
