Abstract

8704. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. April 7. Anthraquinonephenanthridones, which are dves or intermediate products for dyes, are obtained by condensation of o - benzoylaminohalogenanthraquinones or halogen derivatives thereof. Products are specified from the following parent materials:-1-benzoylamino-2-bromanthraquinone, 1:4-dibenzoyldiamino-2 : 3-dichloranthraquinone, 1 - chlor - 2 - benzoylaminoanthraquinone, 2 - benzoylamino - 3 - halogenanthraquinone, 1:5- dichlor - 2:6 - dibenzoyldiaminoanthraquinone, 1:3:5:7-tetrabrom-2:6- dibenzoyldiaminoanthraquinone, o-chlorbenzoyl- 2-amino-1-chloranthraquinone; the chlorine atom can be removed from the last-mentioned product by means of copper powder. Specification 20,338/10 is referred to. Benzoylaminohalogenanthraquinones. - 1:4- Dibenzoylamino - 2:3 - dichloranthraquinone is obtained by chlorinating 1:4-diaminoanthraquinone in an indifferent solvent, and heating the product with benzoyl chloride in nitrobenzene solution; 1:5-dichlor-2:6-dibenzoylaminoanthraquinone is obtained by boiling 1:5-dichlor-2:6- diaminoanthraquinone with benzoyl chloride; 1:3:5:7-tetrabrom-2:6-dibenzoylaminoanthraquinone is obtained by treating 2:6-diaminoanthraquinone with bromine in an indifferent solvent such as glacial. acetic acid, and heating the product with benzoyl chloride in nitrobenzene solution; o-chlorbenzoyl-2-amino-1- chloranthraquinone is obtained by heating ochlorbenzoyl chloride with 1 - chlor - 2 - aminoanthraquinone.
