Tetrachlorophthalic anhydride Usage And Synthesis
  • Chemical Propertieswhite needle-like crystals or powder
  • UsesIntermediate in dyes, pharmaceuticals, plasticizers, and other organic materials; flame-retardant in epoxy resins.
  • DefinitionChEBI: A cyclic dicarboxylic anhydride that is phthalic anhydride chlorinated at the 4-, 5-, 6- and 7-positions.
  • General DescriptionOdorless needle-like crystals or white powder.
  • Air & Water ReactionsSensitive to air and moisture.
  • Reactivity Profile4,5,6,7-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 HazardFlash 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.
  • Purification MethodsCrystallise the anhydride from chloroform or *benzene, then sublime it in a vacuum. [Beilstein 17/11 V 260.]
