    摘要: 1-Amino-2-(6'-hydroxyhexoxy)-4-hydroxyanthraquinone (I) is prepared from the corresponding 2-phenoxy- or 2-halo-anthraquinone compound and 1,6-hexanediol with or without a phenol in the presence of an alkaline agent at elevated temperatures by reacting, per mole of the anthraquinone compound, from 2 to 6 moles of 1,6-hexanediol in the presence of ethylene oxide adducts on phenols or alkanols and/or polyethylene glycols at from 125.degree. to 135.degree. C. and then heating the resulting reaction mixture at from 140.degree. to 150.degree. C., in the course of which the stage 1 byproducts, namely the 1',6'-bis(1-amino-4-hydroxyanthraquinonyloxy)hexane diether is cleaved into (I), leaving a diether level of .ltoreq.2% by weight in (I).

    摘要: The invention discloses a process for the preparation of 1-amino-2-bromo-4-hydroxyanthraquinone by brominating 1-aminoanthraquinone in the 2- and 4-position in concentrated sulfuric acid and subsequently hydrolyzing the 1-amino-2,4-dibromoanthraquinone obtained as intermediate, which process comprises removing excess bromine and/or hydrobromic acid formed during the bromination from the reaction mixture and carrying out the hydrolysis at elevated temperature in the presence of an aldehyde. 1-Amino-2-bromo-4-hydroxyanthraquinone is an important intermediate for dyestuff synthesis and is used in particular for synthesizing anthraquinoid disperse dyes.

    摘要: The present invention relates to a dark colored composition based on liquid crystals, especially for use in a dichroic display cell. It comprises a mixture of liquid crystals and of dyes respectively red, yellow and blue. The red dye is the 4,4'-bis(p-dimethylamino-phenylazo)-2-methyl-azobenzene; the yellow dye is the 4,4'-bis(p-methoxy-phenylazo)-2-methyl-azobenzene; and the blue dye in an anthraquinonic dye of formula (III), ##STR1## in which A is ##STR2## and B is H or ##STR3## where R and R', indentical or different, are a lower alkyl or alkoxy group, one of the A and B being H when the other is not H.
