N-Substituted aminomethylphenol (Mannich base) and 3,4-dihydro-2H-3-substituted 1,3-benzoxazine (benzoxazine) were synthesized from substituted phenol (p-cresol, phenol, p-chlorophenol), substituted aniline (p-toluidine, aniline, p-chloroaniline) and formaldehyde to study influence of substituent on equilibrium of benzoxazine synthesis from Mannich base and formaldehyde. (1)H-NMR and charges of...

In this study, phenol-formaldehyde (PF) resin has been modified with titanium dioxide nanoparticles (nano-TiO2) at a varying ratio from 0.05 wt.% to 1.5 enhance the thermal properties and combustion performance of resins. The effect nano-TiO2 modification on (chemical or thermal) resins was determined by Fourier transform infrared (FT-IR) analysis (TGA) techniques. addition, laminated veneer lu...

This study is to investigate the capability of producing lignin-based phenol-formaldehyde adhesive (LBPFA) with lignin derived from coir pith collected in Mekong Delta, Viet Nam. The LBPFA synthetic process underwent non chemical modifications minimize petrochemicals and energy. Effective factors as reaction time, temperature various contents phenol substitution were examined. Physical, thermal...
