The Uses of Tetrabromophthalic anhydride

tetrabromophthalic anhydride is a reactive flame retardant, can be used for polyester resin, epoxy resin, flame retardant, also can be used for flame retardant for PS, PP, PE, flame-retardant ABS resin.

Definition

ChEBI: Tetrabromophthalic anhydride is a cyclic dicarboxylic anhydride and a member of 2-benzofurans.

General Description

Pale yellow crystalline solid.

Air & Water Reactions

Insoluble in water. Sensitive to moisture .

Reactivity Profile

Tetrabromophthalic anhydride 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.

Hazard

Low toxicity by ingestion, inhalation, and skin contact. A mild eye irritant.

Fire Hazard

Flash point data for Tetrabromophthalic anhydride are not available. Tetrabromophthalic anhydride is probably combustible.
