What is the name of the compound that is used to make dye?
Nitrous acid (HONO) was one of the reagents tried in the early experiments with aniline, and in 1858 the German chemist Johann Peter Griess obtained a yellow compound with dye properties. Although used only briefly commercially, this dye sparked interest in the reaction that became the most important process in the synthetic dye industry. The reaction between nitrous acid and an arylamine yields a highly reactive intermediate; the reaction of this intermediate with phenols and aryl amines is the key step in the synthesis of more than 50 percent of the commercial dyes produced today.
Why are Azo dyes important?
Azo dyes became the most important commercial colorants because of their wide colour range, good fastness properties, and tinctorial strength (colour density), which is twice that of the anthraquinones, the second most important group of dyes. Azo dyes are easily prepared from many readily available, inexpensive compounds and meet the demands of a wide range of end uses. Cost advantages tend to offset the fact that these are less brilliant and less lightfast than the anthraquinones.
What is the second largest group of commercial colorants?
Preparations of derivatives gave a host of anthraquinone dyes that today constitute the second largest group of commercial colorants.

How does sulfuric acid affect water solubility?
Nicholson had independently discovered aniline blue and found that treatment with sulfuric acid greatly increases its water solubility. This process, in which a sulfonic acid group (―SO 3 H) is added onto an aryl ring, was found to be applicable to many dyes and became a standard method for enhancing water solubility. Most of the few hundred triarylmethane dyes listed in the Colour Index were synthesized before 1900. In some, one phenyl ring is replaced with a naphthyl group, whose substituents include NH 2, OH, SO 3 Na, COOH, NO 2, Cl, and alkyl groups. While most substituents act as auxochromes, sulfonates are present only to increase the solubility of the dye, which is also improved by amino groups, hydrochlorides thereof, and hydroxyl groups. Many vat dyes have quinonoid groups that are reduced to soluble, colourless hydroquinones in the vatting operation and then oxidized back to the original dye. Similar reactions are utilized in the developing process in colour photography.
Why are disazo dyes no longer produced?
Until the 1970s derivatives from methyl- or methoxyl-substituted benzidines constituted the major group of disazo dyes, but they are no longer produced in many countries because they are carcinogens.

How do colorants work?
Colorants function through selective electromagnetic absorbance in the visible spectrum. A given pigment or dye molecule absorbs different wavelengths of electromagnetic radiation according to its atomic structure, and local chemical environment. The quantum behavior of a chemical typically results in distinct resonant frequencies of chemical bonds, which can be excited best by discrete wavelengths—meaning broad spectrum radiation has its spectra changed via absorption upon interaction. The physical shape, size, organization and concentration of dyes and pigments can also drastically affect observed color. Pigments are particularly susceptible to altered appearances based on physical properties.
How are dyes and pigments related?
Colorants can be divided into pigments and dyes. Broadly, dyes are soluble and become fixed to a substrate via impregnation, while pigments are insoluble and require a binding agent to adhere to a substrate. Dyes, therefore, must have an affinity for the substance they are intended to color. Chemically speaking, for now, pigments can be organic or inorganic, while dyes are only organic. Furthermore, organic white pigments do not exist, despite the fact that the majority of purified crystalline organic products are white in appearance. This story is complicated somewhat by lake pigments, or lakes, which are dyes modified with a chemical process to form an insoluble pigment. Typically this involves precipitating the natural extracts as salts in alkaline conditions. The historical importance of both pigments and dyes is closely related, as the markets for both, as well as the types and variety available, have always been closely tied.
Why are aniline dyes produced at scale?
Aniline dyes were produced at scale, in part because of many advances in the synthesis of their precursors. Antione Bechamp described a process for reducing nitrobenzene to aniline in 1854, known as the Bechamp Process, making the production of aniline easy.
Why are colorants no longer used?
These conditions became possible due to price drops in reagents due to new industrial preparations like the LeBlanc process, where potassium carbonate formerly obtained from ashes was replaced by sodium carbonate.

What was the Egyptian blue used for?
In ancient Egypt, blue was considered the color of the divine. As a result, the early synthetic compound Egyptian Blue, became an incredibly important pigment. It was used for the depiction of eyes, hair and decoration in the graphic representation of pharaohs. Blue, particularly ultramarine pigment made from ground lapis lazuli remained significant for depictions of the divine through the Renaissance. Pre-industrial revolution painters in Europe used ultramarine almost exclusively for the robes of Mary because of the pigment's great expense, until the work of Jean-Baptiste Guimet and Christian Gmelin made it commercially available in larger, cheaper quantities.
