Abstract: 1,5-DINITROANTHRAQUINONE IS ISOLATED FROM A NITRATION MIXTURE CONTAINING DINITROANTHRAQUINONES BY ALLOWING N-methylpyrrolidone to act on the nitroanthraquinone mixture. From 10 to 45% by weight of the nitroanthraquinone mixture remains undissolved and the undissolved material is separated from the solution. A dinitroanthraquinone is isolated which contains from 75 to 95% by weight of 1,5-dinitroanthraquinone and practically no beta -dinitroanthraquinones.

Abstract: Azo dispersion dyes of formula (I): (in which A is H or methyl, K is the gp. of a coupling component and R is H, aralkyl, aryl, disbustd. mercapto) are useful for dyeing of textiles made from synthetic fibres, e.g. cellulose acetates, polyamides, and esp. polyesters, in yellow to turquoise shades. Intense colours with good fastness, esp. heat- and wet-fastness, are obtained.

Abstract: Isothiazolo-pyrimidin-dione dyes of formula (where R is opt. substd. (cyclo) alkyl, aralkyl, or (hetero)aryl; R' is H or opt. substd. alkyl; and K is the radical of a coupling component) are used in prepns. contg. the other usual constituents, for dyeing polyamides, cellulose esters or esp. synthetic linear polyesters. Strong red to blue dyeing is obtd. with very good fastness, esp. in the red range. Dyeing can be carried out by the high temp. method and often with carriers.

Abstract: 1467386 o-Benzyl toluenes BASF AG 16 July 1974 [17 July 1973] 31396/74 Heading C5E [Also in Division C2] o-Benzyl toluenes of the formula I wherein R 1 are H or halogen, R 2 are H, halogen or an aliphatic or aromatic radical are prepared by reacting an o-xylyl halide of the formula II with a benzene compound of the formula III in the presence of BF 3 activity and associated oxygen-containing acid activity. The BF 3 activity may be provided by free BF 3 or an adduct thereof. The oxygen-containing acid activity may be provided by any acid including a Lewis acid having one or more oxygen atoms in the molecule or in the complex if in adduct form. Consequently both activities may be provided by complexes of BF 3 with water, ethanol, phosphoric acid or ethers. Certain compounds of the formula I are claimed per se namely when (i) R 1 are H or halogen and R 2 are all aromatic; or (ii) one R 1 is halogen, and the other R 1 are H or halogen and R 2 are H or aliphatic; or (iii) all R 1 are H, one R 2 is aromatic, one R 2 is H, halogen or aliphatic and the other R 2 are H, halogen, aliphatic or aromatic; or (iv) all R 1 are H, one R 2 is halogen, one R 2 is aliphatic and the remaining R 2 are H, halogen or aliphatic. Hydrocarbons prepared in the examples are: o-benzyltoluene; 2,3 1 ,4 1 -trimethyldiphenyl methane; and 2-methyl-4 1 -phenyl-diphenyl methane.
