Synthesis of p-Tolylbenzyl Ether by Phase Transfer Catalysis under Microwave Irradiation

The p-tolyl benzyl ether was synthesized by reaction of p-cresol and benzyl chloride in H2O-95% ethanol as solvent by phase transfer catalysis under microwave irradiation.The proper technological conditions were identified as follows: n(p-cresol) : n(benzyl chloride) : n(sodium hydroxide)= 1:1.1:1.1,microwave power 400 W and microwave irradiation time 6 min.The average yield of p-tolyl benzyl ether achieves 96.21%.
