4-Phenylphenol is a colorless solid from the group of phenols .
Extraction and presentation
4-phenylphenol can be obtained by Suzuki coupling of phenylboronic acid with 4-iodophenol in the presence of 10% palladium on charcoal and potassium carbonate are obtained.
properties
4-Phenylphenol is a flammable, hardly flammable, white, flaky solid with a phenol-like odor, which is very sparingly soluble in water.
use
4-Phenylphenol was used in the synthesis of a new polyphosphazene polyelectrolyte as a dispersant of single-walled carbon nanotubes in water. It is also used as a stabilizer for halogenated isoprene / isobutylene rubbers.
