| Hazard Information | Back Directory | [Chemical Properties]
Brownish-yellow needles. Soluble in
dilute alkaline solutions. | [Synthesis]
Flavanthrone is prepared from 1-chloro-
2-phthalimidoanthraquinone via the 2,2'-
diphthalimido-1,1'-bianthraquinonyl, using
copper in boiling trichlorobenzene. The alkaline
ring closure is accomplished by boiling with excess
3 – 5 % sodium hydroxide, which cleaves
both phthalic acid residues simultaneously . Only the unsubstituted flavanthrone is
used as a vat dye and pigment. | [Properties and Applications]
