    Abstract: 1442670 1-Nitroanthraquinone BASF AG 30 Oct 1973 [31 Oct 1972] 50329/73 Heading C2C 1-Nitroanthraquinone is separated from a mixture containing 1-nitro-anthraquinone, optionally in admixture with 2-nitroanthraquinone together with one or more dinitro-substituted anthraquinones, by treating the mixture to effect reaction of the dinitroanthraquinone(s) with a compound containing one or more methylene groups activated by the presence in the compound of one or more carbonyl groups, the reaction being effected in the presence of from 0À1 to 10% by weight based on the total weight of the starting mixture of an initiator for the reaction and in an aprotic polar organic solvent which optionally contains water in an amount of not more than 10% by weight to form a mother liquor containing in dissolved form the material resulting from the reaction together with any 2-nitroanthraquinone present in the starting mixture and containing 1-nitroanthraquinone in undissolved form. The initiator is preferably a compound which yields nitrite, halide, thiocyanate, alcoholate or phenolate ions and the compounds containing activated methylene groups are preferably aliphatic, cycloaliphatic, araliphatic and heterocyclic unsubstituted or substituted ketones, beta-hetocarboxylic esters or amides, betacarbonyl compounds and cyclic carbonamides.

    Abstract: 4,5-Disubstituted thiazoles are manufactured by reacting 4-amino-5-cyano-thiazoles with hydrogen sulfide in the presence of basic compounds, followed by dehydrogenating cyclization. The new 3-amino-thiazolo-(4,5-c)-isothiazoles I, 4-amino-5-thiocarbamidothiazoles III and 4,5-disubstituted thiazoles IV obtainable by the process of the invention are valuable intermediates for the manufacture of azo dyes and of crop protection agents.

    Abstract: A process for the recovery of 1-nitroanthraquinone in a purified state from a nitroanthraquinone mixture containing it by treatment with a base in the presence of an initiator such as nitrite, halide, thiocyanate, alcoholate or phenolate ions in an organic solvent. A 1-nitroanthraquinone is obtained which is essentially pure or contains only small quantities of isomers and dinitroanthraquinones.

    Abstract: Production of pure 1-nitroanthraquinone from nitroanthraquinone mixtures by treating the mixture in an organic aprotic solvent with a primary or secondary amine or a mixture of the same. A pure 1-nitroanthraquinone in which practically no dinitroanthraquinone or other byproducts can be detected is obtained in a high yield. The 1-aminoanthraquinone obtained from this 1-nitroanthraquinone is suitable for all dye syntheses.
