90 °C

In a 500 ml four-neck flask, load 115 g phenol (1.223 mol) and 82.2 g (1.468 mol) of dry KOH. A mass is heated up to 90° C. while mixing. Then by dropping during 0.5 h add 184.7 g (1.223 mol) of amylbromide. Maintain the mixture at a temperature of 95-100° C. for 45 minutes while mixing. After cooling, 200 ml of benzene and 300 ml of water are added to the mixture. The water layer is decanted. Then the benzene layer is washed with 200 ml of 5% solution of NaOH The benzene layer is then washed a few times with water until the reaction mixture is neutral.
