The adsorption of aniline, N-methylaniline and N,N-dimethylaniline on phenol formaldehyde resin(JDW-2) in aqueous solutions under static conditions has been studied. A semi-empirical rate equation adequately fits the sorption rate data of the three anilines in the initial period, that is, the ...
In the present study the recovered tannin was impregnated in phenol-formaldehyde (PF) resin. Spectroscopic and thermogravimetric (IR, NMR, TGA and DSC) studies revealed that the modified polyphenol was held physically in the impregnate. The impregnated matrix showed resistance to mineral acids, ...
Phenol-formaldehyde resin (PF) composites with a nano-porous graphite additive (NPGA) in various contents were fabricated and the wear behaviors under low and high sliding speeds were studied. The addition of NPGA significantly improved the wear resistance of the PF. The specific wear rates of ...

It is shown that at a temperature of 295 K, phenol groups of phenol formaldehyde sorbents are characterized by the value p K 13.0–13.7. It is found that raising the temperature to 343 K reduces the p K value by one. It is concluded that the reason for the lower acidity of phenol for...
The effect of incorporating different loadings of oil palm bio-ash nanoparticles from agriculture waste on the properties of phenol-formaldehyde resin was investigated in this study. The bio-ash filler was used to enhance the performance of phenol-formaldehyde nanocomposites. Phenol-formaldehyde resin fi...
