Abstract
273,774. I. G. Farbenindustrie Akt.- Ges. July 5, 1926, (Convention date]. Addition to 271,884. Anthraquinonyl-alpha-ketones are produced by treating with an acid oxidizing agent benzanthrones having an alkyl or nitrile group in the Bz1- or the Bz2-position or having alkyl groups in both the Bz1- and the Bz2-positions. According to examples the following products are obtained, oxidation being effected by chromic acid in glacial acetic acid :-1-acetylanthraquinone from Bz1 - methvlbenzanthrone (Specification 268,830) or from Bzl : Bz2-dimethylbenzanthrone (Specification 268,830); anthraquinonylmethyldiketone C14H7O2-CO-CO-CH3 from Bz2-methylbenzanthrone (Specification 244,120); two products melting at 297‹ C. (probably C14H7O2- CO-CN) and 276-277‹ C. from benzanthrone- Bz1-nitrile (Specification 243,026). The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use, as parent materials, of benzanthrones having a carboxyl group in the Bz1- or Bz2-position. This subjectmatter does not appear in the Specification as accepted.
