Heterocyclic azo dyes. I. Azo Dyes Containing the Benzotriazole Nucleus

Journal für Praktische Chemie, 1967
AbstractThe synthesis, some dyeing, and fastness properties of several new dispersed, acid, and direct dyes derived from the aminobenzotriazoles (I–IV) and 5‐hydroxybenzotriazole (V) are described. The suitability of the amino derivatives (I–IV) as bases for azoic dyeing has also been studied.

Bioreactors for Azo-Dye Conversion

2010
This chapter embodies two sections. In the first section a survey of the state of the art of azo-dye conversion by means of bacteria is presented, with a focus on reactor design and operational issues. The relevance of thorough characterization of reaction kinetics and yields is discussed.

Undiscovered Mechanism for Pyrogenic Carbonaceous Matter-Mediated Abiotic Transformation of Azo Dyes by Sulfide.

Environmental Science and Technology, 2019
Pyrogenic carbonaceous matter (PCM) catalyzes the transformation of a range of organic pollutants by sulfide in water; however, the mediation mechanisms are not fully understood.

Fast Photoswitching Azo Dyes

Macromolecular Symposia, 2015
SummaryFast photoswitching azobenzene molecules were incorporated into isoflavone moieties. These molecules exhibit a liquid crystalline nematic state at certain temperature intervals. UV/Vis spectrophotometry investigations on solutions reveal that E/Z conversion takes place around 1 s, whereas thermal back relaxation, namely Z/E, takes around 6 min ...

SILICON-CONTAINING AZO DYES

The Journal of Organic Chemistry, 1950
The dyeing properties and the lightfastness on cellulose acetate rayon of several azo dyes prepared from m-trimethylsilyl- and m-triphenylsilyl-N,N]- bis- (β-hydroxyethyl)-aniline have been examined.The dyes derived from m-triphenylsilyl-N,N-bis-(β-hydroxyethyl)-aniline have been found to lack substantivity for cellulose acetate and to have inferior ...

Bioaugmentation of Azo Dyes

2010
Biodegradation is a cost-effective method to remove the residues of azo dyes prior to their discharge in wastewater streams from dye product industries. The efficacy of this treatment method is highly dependent on establishing an effective degrader community and maintaining environmental conditions that support the growth and activity of the degrader ...
