Abstract

Dyes are made by reacting acid condensing agents with anthraquinone - 2.1(N) - 1.21(N)-benzacridones containing an a -aminoanthraquinone radical in 4-position and also in Bz.3, Bz.4, Bz.5 or Bz.6-position, and having in each nucleus one free o-position with respect to the imino group or the said o-positions being wholly or partly replaced by substituents which do not prevent ring-closure. If desired, the products may be after-oxidized, e.g. with sodium hypochlorite. The starting materials are obtained by reacting polyhalogen-anthra-quinone-benzacridones having a replaceable halogen atom in 4-position only of the anthraquinone nucleus and one or more halogens in the Bz.-positions with a -aminoanthraquinones. The Bz.-ring may contain halogen atoms, alkyl radicles or alkoxy groups, and the a -amino-anthraquinone radicles may contain halogen atoms or aroylamino groups. Condensing agents specified are aluminium chloride in solvents such as nitrobenzene, and also concentrated sulphuric acid or chlorsulphonic acid. Any aroyl residues saponified during the condensation may be reintroduced by aroylation. The products dye vegetable fibres yellowish-brown, khaki, or olive shades. In examples: (1) 4.61-dichloranthraquinone-2.1 (N)-11.21(N)-benzene acridone is reacted in naphthalene in presence of potassium carbonate and copper acetate with 1-aminoanthraquinone followed by ring-closure with aluminium chloride in nitrobenzene and oxidation with sodium hypochlorite or with 1-amino-5-benzoylaminoanthraquinone followed by ring-closure with sulphuric acid monohydrate; (2) 4.31.61-trichloranthraquinone - 2.1(N) - 11.21(N) - benzene acridone is reacted with 1-aminoanthraquinone, followed by ring-closure; (3) 31.51. 61.4 - tetrachloranthraquinone - 2.1(N) - 11.21 (N)-benzene acridone is reacted with 1-amino-anthraquinone, 6-chloro-1-aminoanthraquinone, or with 1-amino-5-benzoylaminoanthraquinone, followed by ring-closure, and in the case of the last-mentioned body by re-benzoylation; (4) 31.41.51.61.4 - pentachloranthraquinon -2.1(N)11.21(N)-benzene acridone is reacted with 1-aminoanthraquinone, followed by ring-closure; (5) 31-methoxy-61.4-dichloranthraquinone-2.1(N) -11.21(N)-benzene acridone is reacted with 1-aminoanthraquinone, followed by ring-closure; (6) the bromo-dichloro-anthraquinone-acridone obtained according to example 1 or 2 of Specification 327,758, is reacted with 1-amino-5-benzoylaminoanthraquinone in naphthalene in presence of sodium acetate, magnesium oxide, and copper chloride, followed by ring-closure; (7) the dibromochloranthraquin-one-acridone obtained according to example 4 of Specification 327,758, [Class 2 (iii)], is reacted with 1-amino-5-benzoylaminoanthraquinone or with 1-aminoanthraquinone as in (6), followed by ring-closure. Specifications 361,423, 439,180, and 451,859 also are referred to.
