✦ Synopsis

Phenols can be converted into their acetates directly in a dilute aqueous solution by a simple reaction with acetic anhydride'-3. The method used for the isolation and concentration of phenol acetates from water is usually repeated liquid-liquid extraction with subsequent concentration of the derivatives by solvent evaporation. Another enrichment method uses solid-phase extraction of phenols from acidified water samples, elution with an organic solvent, derivatization of phenols in the eluate and gas chromatographic (GC) analysis 4q5 Retention data and mass spectra of .
