摘要：

A new procedure was developed for the liquid-liquid extraction of phenols from aqueous solutions with acetonitrile. It is based on the ability of aqueous acetonitrile systems to form immiscible phases in the temperature range 271-269 K. The resulting duration of analysis is 40-45 min, the partition coefficient is 45-140, and the recovery is 97.8-99.2%. The procedure was proved applicable for sample pretreatment followed by determination by reversed-phase HPLC.
