The decolourization of the azo dye Acid Orange 7 was investigated using a heterogeneous photocatalysis which comprised irradiating aqueous solutions of the dye with UV light at a wavelength of 254 nm in the presence of either (TiO 2 + ZnO) mixture, [ ( Ti O 2 + ZnO ) / S 2 O 8 2...

Azocolourants and Azodyesare one group of synthetic dyestuffs based on nitrogen that are often used in textile industry. Some AZO dye stuffs may break down under certain conditions to produce carcinogenic and allergenic aromatic amines. Azocolourants and Azodyes and REACH annex XVII Azocolourants ...
Aniline dye is usually referred to as "aniline colour". Previously, azo dyes were used as aniline paints. However, use of azo dyestuff (coal tar dyestuffs) is no longer allowed as it is harmful to health and is only found, if at all, in cheap imported leather goods. Components of ...

Tartrazine is synthetic lemon yellow AZO dye that finds use as food coloring agent. It is derived from petroleum and is water soluble with maximum absorbance in aqueous solution. It finds use in many of the products including processed commercial foods having artificial green or yellow color, dess...
The method of synthesis of azo dyes presented in Scheme 1 can be done by using phenolic compounds extracted from the nCNSL. Using phenols extracted from nCNSL (anacardic acid, cardol and cardanol), the substituted aniline can be prepared by nitrating one of the phenols followed by catalytic re...
Effects of molecular structure on dyeing performance and colour fastness of yellow dyestuffs applied to polypropylene fibres in supercritical carbon dioxide Thirteen dyestuffs of four chemical classes (quinophthalone, anthraquinone, isothiazole-fused anthrone and pyridone azo) were applied for the dyeing of...
