Usage

Preparation

1,4-Diamino anthraquinone? in oblate sulfuric acid.

Safety Profile

Poison by intravenous route. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Properties and Applications

bright blue purple. Dark blue powder. Soluble in ethanol, acetone and benzene. The strong sulfuric acid dyes for brown, diluted into blue purple. Dyeing meet copper, iron ions become lighter in color, a red light. Used for polyester and their blended fabric dyeing, also can be used in the vinegar fiber, three vinegar fiber, acrylic and polyamide fiber dyeing. Can also be used for the plastic coloring and dyes as solvent. This product is suitable for dyeing of high temperature and high pressure, the dyeing speed medium, levelness and dye deep sex are good. polyester / wool dyeing method for carrier, but the sun fastness are lower class I, polyester/cotton blended with suitable for in light color. Two vinegar fiber dyed red to blue, the dyeing speed faster, the levelness and dye deep sex are preferable, and is suitable for dyeing fastness of the sun higher fabric, dyed fiber is red light three vinegar, dyeing nylon colored light is blue, levelness and dye deep sex all good, acrylic dyeing color and two vinegar similar fibre, the dyeing rate is low, with only light color. Often used for direct printing polyester fabric. Also used in two vinegar fiber, three vinegar fiber fabric printing of polyamide or directly, cannot be the impression of discharge printing.

Process for the manufacture of 1,4-diamino-5-nitroanthraquinone

A process for the manufacture of 1,4-diamino-5-nitroanthraquinone from 1,4-diaminoanthraquinone by nitration with mixed nitric and sulphuric acid, before which nitration a masking of the two amino groups to form 1,9-4,10-anthraquinone disulphonimide takes place, this intermediate being in turn split by hydrolysis after the nitration, which process comprises carrying out the masking of the 1,4-diaminoanthraquinone to form the 1,9-4,10-anthraquinone-disulphonimide with liquid sulphur trioxide and carrying out the entire nitration process by using liquid solvents which are inert towards the reactants.
