Abstract

This project aims to develop a Biofenol production strategy (phenols from pyrolytic oils from wood) for use in the synthesis of renewable adhesives for bonding wood. The chain of obtaining Biofenol begins with the slow pyrolysis (carbonization) of wood, a process widely used in Brazil for charcoal production, input from iron and steel industry. The resulting smoke of the carbonization is condensed and, by decantation, the insoluble tar is removed. This tar is distilled off and the phenolic moiety is drawn between 180 ° C and 230 ° C. This material is subsequently subjected to a demethylation reaction which active positions of the phenol contained in tar distillate to carry out the synthesis with formaldehyde adhesives. Between 2014 and 2015 this project received angel investment of $ 180,000 to demonstrate the technical feasibility of producing adhesives for bonding wood completely replacing the petrochemical phenol by Biofenol. At this stage of development our challenges will be to replace the demethylation reagent and improve the adhesive characteristics produced with the Biofenol. (AU)
