Description

Violanthrone, Indanthren Dark Blue BOA,is generated by potash fusion of benzanthrone , . Direct potash fusion leads to side products, such as isoviolanthrone and 4-hydroxybenzanthrone. The crude product may be used directly or in mixtures with other dyes in vat dyeing. It is also used to generate violanthrone derivatives. Several processes have been developed to decrease the amounts of undesirable side products of the direct potash fusion of benzanthrone or to purify the bibenzanthronyl or the crude violanthrone . Especially effective is the addition of high-boiling solvents such as naphthalene, the so-called low carbazole anthracene residues, or sodium acetate to the melt. The quality of the products prepared by these methods is satisfactory for the production of almost all violanthrone dyes.
