Verwenden
3-Nitrophthalic Acid is a useful chemical in organic synthesis. It is also an impurity of Apremilast.
synthetische
Phthalic anhydride was added to concentrated sulfuric acid, stirring under the passage of water vapor heating to 80 °C, fuming nitric acid was added dropwise, the reaction temperature to maintain 100-110°C, add the end of the heat above 110°C for 2h, placed in the overnight pour into the water, and filtered. The filter cake was recrystallized with water to obtain 3-Nitrophthalic acid. Yield of about 30%.
Allgemeine Beschreibung
3-Nitrophthalic acid is a degradation product of isoxaben herbicide. It acts as ligand and forms rare-earth complexes.
Sicherheitsprofil
A preparative hazard. When heated to decomposition it emits toxic fumes of NOx.
l?uterung methode
Crystallise 3-nitrophthalic acid from hot water (1.5mL/g). Dry it in air. The amide has m 201o (from EtOH). [Beilstein 9 H 823, 9 IV 3275.]
