disodium 6-acetamido-4-hydroxy-3-[[4-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]azo]naphthalene-2-sulphonate

Chemical Properties

Red powder. Solubility in water is 120g/L (20℃), 150g/L (80℃). The color light is slightly dark when it meets iron ions and turns dark when it meets copper ions. The dye has high reactivity and medium affinity.

Uses

Reactive orange 16 is common textile dyes that can be adsorbed onto single-walled carbon nanotubes (SWCNTs) through electrostatic interactions, allowing the separation of residual dyes.

Definition

ChEBI: An azo compound having a ({[(2-sulfonatooxy)ethyl]sulfonyl}phenyl)diazenyl moiety attached at position 2 of a multi-substituted naphthalene.

Preparation

2-(4-Aminophenylsulfonyl)ethyl hydrogen sulfate diazo, and 6-Acetamido-4-hydroxynaphthalene-2-sulfonic acid coupling.

Properties and Applications

Reactive Orange 16 is a bright yellow orange. Red powder.20 ℃ in the solubility of water when for 120 g/L, in 80℃ when more than 150 ℃ the solubility of g/L. After dyeing color shade of red light for yellow. In dye bath of iron ion in color shade darker; Copper ions in color shade darker.the dye affinity medium, the reaction of the high.Used for cotton or viscose fiber dyeing, also can be used for cotton and viscose fiber in law or a two-phase method printing.
