Abstract

Chlorinated dibenzanthrone dyes which dye cotton in reddish-violet shades from the vat are prepared by chlorinating dibenzanthrone in presence of chlorsulphonic acid or mixtures containing it. In examples the chlorination is effected in chlorsulphonic acid, or in a mixture of chlorsulphonic acid and sulphuric acid monohydrate in presence of ferric chloride. Specification 22519/05 is referred to. p
