DISPERSE ORANGE 3 Chemical Properties,Uses,Production

Description

Disperse orange 3 is an azo dye which can induce contact dermatitis in workers in the textile industry. Patch tests are frequently positive (about 30%) in hairdressers with a hand dermatitis. It is probably an indicator of contact sensitization to PPD, but disperse orange 3 can also be found in so me semipermanent hair dyes.

Chemical Properties

red to dark brown powder

Uses

Disperse Orange 3 may be used as a test material for investigating its degradation by the white rot fungus?Pleurotus ostreatus and the products obtained upon degradation are determined using UV-visible spectrophotometric and high-performance liquid chromatographic techniques.

Uses

Disperse orange 3 is used as a dye in acetate, nylon, silk, wool, and cotton; stocking dye.

Preparation

4-Nitrobenzenamine diazo, with aniline base armour sulfonic acid coupling, and sodium hydroxide solution to boil, then a sulfonic acid hydrolysis off base.

Definition

ChEBI: Azobenzene substituted at the phenyl 4-positions by an amino and a nitro group.

General Description

Disperse Orange 3 (DO3) is a monoazo dye, which contains 90% dye content plus dispersing agents and surfactants. It has two aromatic rings with an amino group on one of the rings and the other is substituted with a nitro group. It shows an absorption peak majoring at 415 nm.

Contact allergens

Disperse Orange 3 is an azo dye that can induce contact dermatitis in workers in the textile industry. It is positive in a great majority of PPD-positive people, because of hydrolysis in the skin into PPD. Disperse Orange 3 can also be found in some semipermanent hair dyes.

Properties and Applications

Orange, yellow light red powder, melting point of 210-220 ℃. Soluble in ethanol, acetone, toluene, soluble fiber element. The strong sulfuric acid for green light yellow to orange diluted; Nitric acid solution for orange red; In strong hydrochloric acid for brown in the light yellow. Used for polyester and acetic acid fiber dyeing, also can be used for nylon 66 and acrylic fiber dyeing and plastic shading.
