Chemische Eigenschaften
slight yellow powder
Verwenden
4-Nitrophthalimide is used as intermediate of organic synthesis and fluorescent dyes, it can be used to produce azo dyes, luminol, etc. It can also be used to prepare 4-nitrophthalonitrile, 5-cyanophthalide and other drug intermediates.
synthetische
4-Nitrophthalimide is synthesized from phthalimide by nitration. Cool the fuming nitric acid to below 5°C, slowly add concentrated sulfuric acid dropwise, and control the temperature to 10-13°C. Plus phthalimide. Leave at room temperature overnight. Then, it was poured into ice water with stirring, and the precipitate was precipitated below 20°C. Filter, wash with water, dry, and then recrystallize from ethanol to obtain 4-nitrophthalimide with a yield of 60%.
Allgemeine Beschreibung
Yellow powder.
Air & Water Reaktionen
4-Nitrophthalimide can be hydrolyzed. . Insoluble in water.
Reaktivit?t anzeigen
A nitrated amine. Amines are combustible. The combustion of amines yields noxious NOx. REACTIVITY - Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
