Abstract: Phenolated orange seed oil was used in preparing thermosetting and thermoplastic resins. It was also substituted with sulphur to prepare sulphonated-phenolated feedstock that was also used to prepare another thermoset. The products obtained were characterized using Perkin Elmer infra-red spectrometer (FT-IR) and a Bruker av400 MHz NMR for proton Nuclear Magnetic resonance only (1NMR). FT-IR results show several peaks in the aromatic region between 882.00cm-1 and 592.00cm-1 and a carbonyl group of an ester at 1733.00cm-1 for the phenolated vegetable oil. The thermoset obtained from the phenolated vegetable oil shows absorption at 442.56cm-1 due to C-H bend of benzene. The Sulphonated- thermoset has an aromatic peak at 402.35cm-1 and a phenolic O-H at 3429.00cm-1. The thermoplastic shows majorly C-H stretch of an aldehyde at 2920.00cm-1 and the carbonyl group of an aldehyde at 1730.00cm-1. The proton nuclear magnetic resonance shows free benzene protons for all the products in the range 6.00-8.00ppm. These results show that all the products contain phenolic group and hence can compete as phenolic resins. The products are environmental friendly adhesives that contributes to the reduction of panel formaldehyde and phenolic hazards. They are low cost but highly effective resins for end users.
