Reaction Conditions:

with aluminum (III) chloride;iron(III) chloride at 0 - 5; for 6 h;Large scale;

Steps:

1
300 L of pure benzene was placed in a 1000 L enamel reactor, and stirring was started. 40 kg of ferric chloride and13 kg ofaluminum trichloride were introduced, andfreezing was started to lower the temperature in the reactor to 0 °C. 44kg of tert-amyl alcohol was added dropwise, the temperature was controlled at 0-5 °C, andafter theaddition was completed, the temperature waskept for 6 hours. After the end of the heat preservation, 500 kg of water was added, stirred for 5 minutes, and allowed to stand for 1 hour, and the lower layer of wastewater was separated.The distillation was carried out in another distillation still, and the pure benzene was distilled off under normal pressure. The pure benzene was continuously applied, and then distilled under reduced pressure to obtain 99.4% or moreof the product tert-amylbenzene
