| Hazard Information | Back Directory | [General Description]
Odorless needle-like crystals or white powder. | [Reactivity Profile]
TETRACHLOROPHTHALIC ANHYDRIDE(117-08-8) 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. | [Air & Water Reactions]
Sensitive to air and moisture. | [Fire Hazard]
Flash point data for this chemical are not available. TETRACHLOROPHTHALIC ANHYDRIDE is probably combustible. | [Chemical Properties]
white needle-like crystals or powder | [Definition]
ChEBI: A cyclic dicarboxylic anhydride that is phthalic anhydride chlorinated at the 4-, 5-, 6- and 7-positions. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
Crystallise the anhydride from chloroform or *benzene, then sublime it in a vacuum. [Beilstein 17/11 V 260.] |
