Tetrachlorophthalic anhydride Chemical Properties,Usage,Production

Chemical Properties

white needle-like crystals or powder

Uses

Intermediate in dyes, pharmaceuticals, plasticizers, and other organic materials; flame-retardant in epoxy resins.

Uses

Tetrachlorophthalic Anhydride is used in the synthesis of nucleoside analogues with a specific structure as apoptosis inducing active compounds. Also used in the synthesis of carbonic anhydrase inhbitors. Chlorinated Reactive Flame Retardant Intermediate

Definition

ChEBI: A cyclic dicarboxylic anhydride that is phthalic anhydride chlorinated at the 4-, 5-, 6- and 7-positions.

General Description

Odorless needle-like crystals or white powder.

Air & Water Reactions

Sensitive to air and moisture.

Reactivity Profile

4,5,6,7-Tetrachloro-1,3-isobenzofurandione reacts exothermically with water. This reaction is expected to be slow, but can become vigorous if local heating accelerates it. Reaction with water is accelerated by acids. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.

Fire Hazard

Flash point data for 4,5,6,7-Tetrachloro-1,3-isobenzofurandione are not available. 4,5,6,7-Tetrachloro-1,3-isobenzofurandione is probably combustible.

Flammability and Explosibility

Not classified

Purification Methods

Crystallise the anhydride from chloroform or *benzene, then sublime it in a vacuum. [Beilstein 17/11 V 260.]
