Nature:
-Appearance: 4-aminonaphthalene anhydride is a white crystalline solid.
-Melting point: About 187-189 degrees Celsius.
-Solubility: It is almost insoluble in water, but can be dissolved under acidic conditions.
Use:
-4-aminonaphthalene anhydride is commonly used in the field of dyes, pesticides and medicine in organic synthesis.
-It can be used as an intermediate for the synthesis of quinoline, aluminum and magnesium alloys, and amino acids.
Method:
The preparation of 4-aminonaphthalene anhydride is usually carried out by the following steps:
1.4-chloronaphthalene and ammonia are reacted in an appropriate solvent (such as sodium chloride solution) to generate 4-aminonaphthalene.
2. The 4-aminonaphthalene is oxidized, and an oxidizing agent such as potassium permanganate (KMnO4) can be used.
3.4-aminonaphthalene is converted into 4-aminonaphthalene anhydride by heating reaction.
