3,6-Dichlorophthalic anhydride Chemical Properties,Usage,Production

  • Chemical Properties off-white to white powder
  • Uses 3,6-Dichlorophthalic Anhydride is an intermediate in the synthesis of phthalic compounds, phthalazines, and quinones with antimicrobial activity.
  • Purification Methods Boil the anhydride in xylene (allowing any vapours which would contain H2O to be removed, e.g. Dean and Stark trap), which causes any acid present to dehydrate to the anhydride, and cool. Recrystallise it from xylene [Villiger Chem Ber 42 3539 1909, Fedoorow Izv Akad Nauk SSSR Otd Khim Nauk 397 1948, Chem Abstr 1585 1948]. [Beilstein 17/11 V 260.]
