C.I. Reactive Black 5 (17095-24-8) |
| Hazard Information | Back Directory | [Definition]
ChEBI: A bis(azo) compound with two aryldiazenyl moieties placed at positions 2 and 7 of a multi-substituted naphthalene. | [Chemical Properties]
Black powder. Solubility in water (20°C) is 100g/L. The aqueous solution is bluish-black. Adding 1mol/L sodium hydroxide does not change the color. Adding hydrosulfite and warming it turns it yellow-brown. Adding sodium perborate does not restore the color to its original color. It is bluish-green in concentrated sulfuric acid and grayish-blue upon dilution. It is brown in concentrated nitric acid and light brown upon dilution. | [Uses]
Reactive Black 5 (RB5) has been:
- used in an optimization study on the photocatalytic degradation of RB5 dye in synthetic greywater effluent (i.e. aqueous RB5 in distilled water), in order to understand the effects of different photoreactor parameters on the degradation kinetics.
- as a textile dye to investigate the anaerobic reduction in upflow stirred packed-bed reactors (USPBRs) with biological activated carbon (BAC) system
- used in the performance evaluation of dye removal forlarge molecule substance
| [Uses]
C.I.Reactive Black 5 can be used for Ink jet recording apparatus and ink jet method reducing clogging during textile printing | [General Description]
Reactive Black 5 belongs to the class of textile azo dyes. It can be biodegraded by the laccase enzyme in Ganoderma lucidum. |
