3-나이트로프탈산 C화학적 특성, 용도, 생산
화학적 성질
Pale yellow crystals. soluble in hot water, methanol, ethanol, slightly soluble in ether, insoluble in chloroform, carbon tetrachloride, carbon disulfide, benzene.용도
3-Nitrophthalic Acid is a useful chemical in organic synthesis. It is also an impurity of Apremilast.제조 방법
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%.일반 설명
3-Nitrophthalic acid is a degradation product of isoxaben herbicide. It acts as ligand and forms rare-earth complexes.Safety Profile
A preparative hazard. When heated to decomposition it emits toxic fumes of NOx.Purification Methods
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.]3-나이트로프탈산 준비 용품 및 원자재
