## Abstract Phenanthreneβformaldehyde resins of different oxygen content were reacted with phenol 110Β°C in the presence of a strong acid catalyst. Cleavage occurred at the dimethylene ether and acetal bridges joining the aromatic nuclei with the concomitant formation of phenanthreneβformaldehydeβph
Corn bran (CB) was liquefied in the presence of phenol at high temperature (200Β°C) under high pressure (ΟΎ1 atm) and the obtained liquefied products were reacted with formaldehyde to get phenolated CB/phenol/formaldehyde resins with excellent yields. The properties of the cocondensed resins were exam
