    Abstract: Coloured polystyrene or styrene copolymers contain as dye up to 2% of dissolved anthraquinone - 2,1(N) - 11, 21(N) - benzacriolone, or anthraquinone - 2,1(N) - 11,21(N) - naphthacriolone, i.e. where rings I and II may be substituted by halogen atoms or alkyl groups. The styrene copolymers may contain butadiene, e.g. 10% acrylonitrile or acrylic esters. A number of the acriolone dyes are specified. The dyes are brought into a finely divided form before use. The compositions may be granulated before being molded or shaped into articles.

    Abstract: Linear-trans-quinacridones are prepared by reacting a 2,5-dianilino-terephthalic acid, which may be substituted by one or more halogen atoms or methyl or ethyl groups, with benzoyl bromide or benzotrichloride at temperatures between about 140 DEG and 250 DEG C. The process is preferably carried out in the presence of inert organic solvents or diluents, such as nitrobenzene, trichlorobenzene, N-methyl-pyrrolidone or naphthalene. In an example, 2,5-dianilino-terephthalic acid is heated to 175 DEG C. in nitrobenzene and benzotrichloride is run into the reaction mixture which is heated at 180 DEG C. for 5 hours, filtered, the residue washed with nitrobenzene, mixed with sodium carbonate, and finally treated with steam to give linear - trans - quinacridone. Specifications 896,803 and 917,830 are referred to.

    Abstract: 3 - Aminoanthraquinone - 2: 1(N) - 11: 21(N)-benzacridones of the formula of the formula or a Bz-halo-derivative thereof are made by heating the corresponding 3-halo-anthraquinone - benzacridone or a Bz - halo - derivative thereof with urea in an inert organic diluent. 3 - Chloro - 51 - bromo - anthraquinone - benzacridone is made by brominating 3-chloroanthraquinone-benzacridone with bromine at 160 DEG C. 3 : 31 : 51 - Trichloroanthraquinone - benzacridone is made by heating 3-chloro-anthraquinone-benzacridone with thionyl chloride in trichlorobenzene. U.S.A. Specifications 2,111,091 and 2,133,274 are referred to.

    IPC: C09B48/00

    Abstract: Linear-trans-quinacridones are made by heating a 2: 5-dianilinoterephthalic acid with phosgene in the presence of an organic compound which is inert and liquid under the reaction conditions or a mixture of such compounds to a temperature of about 140 DEG to 250 DEG C. Organic compounds specified are nitrobenzene, trichlorobenzene, naphthalene and N-methylpyrrolidone. The terephthalic acid may contain one or more halogen, alkoxy or alkyl substituents on the anilino, radicals. Specifications 896,803, 924,661, 924,662 and Belgian Specifications 579,525, 583,317 and 586,007 are referred to.
