Fast pyrolysis of biomass produces an oil, that can be upgraded to a phenolic and neutrals (PN) fraction suitable for incorporation into phenol formaldehyde resins. The formaldehyde reactivity of several phenolic model compounds commonly found in the PN fraction of pyrolysis oils was studied under a variety of reaction conditions, including temperature, pH, and formaldehyde ratio. The formaldehyde reactivity of the PN model compounds appears to be greater than that of phenol. The PN fraction of pyrolysis oils was also incorporated into phenol formaldehyde (PF) resins and cured. The chemical structure PN-PF resins synthesized and cured under different conditions was monitored with solid state nuclear magnetic resonance spectroscopy. These studies indicate that the PN fraction of pyrolysis oils are highly reactive under commercial resin synthesis conditions and are chemically incorporated into the cured PF resin network.
