Related Products of 3638-73-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3638-73-1, name is 2,5-Dibromoaniline belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
3. Synthesis of 2,5-dibromophenol; Sodium nitrite (65.2 mmol) was added in several portions to a solution of 2,5-dibromobenzenamine (55.8 mmol) in trifluoroacetic acid (80 mL) at 0 C. The resulting solution was added to a boiling solution of sodium sulfate (10 g) in 50% sulfuric acid (120 mL) and the reaction mixture was maintained at reflux for 1 h. Then the product was steam-distilled and the distillate was extracted with dichloromethane (2¡Á200 mL). The combined organic layers were dried (sodium sulfate) and concentrated to provide 2,5-dibromophenol in 41% yield as a yellow solid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2,5-Dibromoaniline, other downstream synthetic routes, hurry up and to see.
