FLAVANTHRONE Chemical Properties,Usage,Production

Chemical Properties

Brownish-yellow needles. Soluble in dilute alkaline solutions.

Uses

Vat dye for textiles, etc.

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.
