چکیده مقاله :
In this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid PEG1000-DAIL[BF4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. This novel methodnot only enhanced the yield, but also made the operating units easy workup. The catalytic system can berecycled or reused without any significant loss of catalytic activity. The mechanism of hydrolysis reactionand the process of catalysis in the thermoregulated ionic liquid bi-phase system were also proposed.
