4-Nitrophthalic anhydride Usage And Synthesis

Chemical Properties

off-white to light yellow-brown powder

Uses

5-Nitrophthalic Anhydride is used in the preparation of phthalic acids as well as compounds with anticonvulsant activities.

General Description

Yellow powder.

Air & Water Reactions

Reacts with water. The organic acids produced by this reaction are significantly more soluble in water.

Reactivity Profile

4-Nitrophthalic anhydride reacts exothermically with water. The reactions are usually slow, but might become violent if local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.

Fire Hazard

Flash point data for 4-Nitrophthalic anhydride are not available, however 4-Nitrophthalic anhydride is probably combustible.

Purification Methods

Distil the anhydride in a vacuum and/or recrystallise it from *C6H6 or Et2O/pet ether. Dry it in vacuo. It forms addition compounds with anthracene (m 118o), and phenanthrene (m 96o). [Beilstein 17 III/IV 6150, 17/11 V 267.]
