Reaction Conditions:
with oxygen;nitric acid in methanol at 20; for 2 h;Sealed tube;
Steps:
1-2 Example 1: Preparation of chlorinated p-benzoquinone.
General procedure: In a 1000 mL closed four-neck reaction flask, 600 g of methanol and 197.5 g of 2,4,6-trichlorophenol were added.Stir the solution, then add 200 mL of 5% dilute nitric acid in a 2000 mL sealed four-neck reaction flask.Start to add the dissolved 2,4,6-trichlorophenol solution, pass 2 atm of oxygen, stir the temperature control at 20 ° C, and react for 2 h.After completion of the reaction, 167 g of chlorinated-p-benzoquinone was obtained by filtration, and the yield was 93.3%.
