Abstract:

In order to improve the coke residue of phenolic resins (PF), different solvents were used in the present work. The research indicates that in comparison with other solvents, such as ethylene glycol (EG) and ethyl silicate (ES), furfural (FF) can enhance crosslinking density and increase residual coke yield of phenolic resins (PF). The results demonstrate that the residual coke yield of PF with furfural is 68 % higher than that with other solvents. In addition, pyrolysis peak temperature of PF with furfural is relatively high and pyrolysis process is more smoothly. FTIR results show that new bonds formed in PF when take furfural as solvent, and furfural changed the structure of phenolic resins. Raman spectra analysis results show that the order degree of the carbonized products (treated at 800 °C) is higher than that in other solvents, and stability of the carbonized products is improved. The research concludes that the type of solvent has great influence on the structure and coke residue.
