Usage

Description

1,4-DIAMINO-5-NITROANTHRAQUINONE is a bright blue-purple dye with a dark blue powder form. It is soluble in ethanol, acetone, and benzene. The dye exhibits a brown color when in contact with strong sulfuric acid and turns blue-purple when diluted. The color lightens in the presence of copper and iron ions and emits a red hue.

Uses

Used in Textile Industry:
1,4-DIAMINO-5-NITROANTHRAQUINONE is used as a dye for polyester and their blended fabrics, as well as in the dyeing of vinegar fiber, three vinegar fiber, acrylic, and polyamide fiber. It is suitable for high-temperature and high-pressure dyeing methods, offering medium dyeing speed, good levelness, and deep color.
Used in Plastic Coloring:
1,4-DIAMINO-5-NITROANTHRAQUINONE is also used for coloring plastics and as a solvent dye.
Standard:
The dye has the following ratings for various fastness standards:
Ironing Fastness: ISO 4-5, AATCC 4
Light Fastness: ISO 3-4, AATCC 3
Perspiration Fastness: ISO 6, AATCC 5
Washing Fastness: ISO 5, AATCC 5
Fading: ISO 4-5, AATCC 4
Stain: ISO 4-5, AATCC 5
These ratings indicate the dye's performance in terms of colorfastness to various conditions such as ironing, light exposure, perspiration, and washing.

Preparation

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

Safety Profile

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.
