Quick definitions from WordNet (aniline dye) noun: any of many dyes made from aniline Synthetic dyes have taken over the industry because of less cost and more reliability but natural dyes such as haematoxylin, carmine and orcein are still in use in the industry. These dyes have no affinity for polyester, cellulosic, or polyamide polymers, since such substrates cannot form an ionic bond with them. The method for the production of Mauve (mauveine) was discovered in 1856 in England by William Perkin. (iii) Aniline dyes can also be used for identification of bacteria on the basis of varying degree of susceptibility of bacteria to different concentrations of the dyes. aniline: 1 n oily poisonous liquid amine obtained from nitrobenzene and used to make dyes and plastics and medicines Synonyms: aminobenzine , aniline oil , phenylamine Type of: amine , aminoalkane a compound derived from ammonia by replacing hydrogen atoms by univalent hydrocarbon radicals Stains and dyes produce different looks because they color wood in different ways. stains are used commonly in microbiology to increase the contrast between microorganisms or parts of its and the background,so that it can be easily visible. Aniline and its derivatives are an important cause of serious industrial poisoning.

Dyes less frequently used with Picric Acid include Aniline Blue, indigocarmine and ponceau S . Aniline was first isolated from the destructive distillation of indigo in 1826 by Otto Unverdorben. Pure pigment stains only partially penetrate the wood, doing most of their coloring by lodging in tiny surface cracks and pores. For example, Flores et al. Examples of wooden toy parts (left to right) stained with forest green, ruby, bright blue, brilliant crimson, peacock blue, lemon yellow. A.W. 56Z0810 - Set of 6 Anilines (1 of ea.) Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1. (iii) Direct Dyes As the name suggest these dyes can be directly applied to the fabrics from their aqueous solution. o-Toluidine and aniline are aromatic amines used as intermediates in the manufacture of a variety of dyes, pharmaceuticals, pesticides, and chemicals employed in the manufacture of rubber. Aniline black may be continuously developed on cotton using large volume of padding liquor. von Hofmann investigated these variously prepared substances, and proved them to be identical, and thenceforth they took their place as one body, under the name aniline or phenylamine. Description; Care And Use; Description. While not raising the grain, alcohol and solvent soluble dyes dry too fast to apply a primary color over large areas without having visible overlaps. ANILINE DYES Water Soluble Transparent Dye Powder The water soluble anilines are best choice for light fastness, transparency of colour, accentuating the wood grain, ease of application, lack of lap marks and use under lacquer and other finishes. Sulfanilamide is one of the sulfa drugs which were widely used as antibacterial in the early 20th century. Cationic dyes for acrylic substrates were initially known as basic dyes, an example of which is C.I. Other dyes are mainly of industrial interest and not for microscopy. Triphenylmethane Dyes Malachite Green Pararosaniline Rosaniline Crystal Violet Xanthene Dyes Fluorescene Eosin Rhodamine B Phthaeleins Phenolphthalein Indigoid and Thioindigoid Dyes Preparation of Indigo Structure of Indigo … • Developing dyes,e.g. Basic Red 18 (Figure 9). See the photo above for examples, of coloring curly maple. In second and third vessels, potassium ferrocyanide (50 kg) and NaClO 3 (30 kg) are dissolved separately in 200 l of water each. Figure 3. Synonyms for Aniline dyes in Free Thesaurus. It ignites readily, burning with a smoky flame characteristic of aromatic compounds. For example, sulfonation of aniline produces sulfanilic acid, which can be converted to sulfanilamide. Two approaches to combinatorial syntheses are employed. Examples. Experiment 19: Combinatorial Synthesis of Azo Dyes When a new pharmaceutical is needed to treat a medical condition, modern ... An example of a class of drugs that was explored using combinatorial methods are the benzodiazepines, which are used to treat anxiety disorders. https://www.woodmagazine.com/materials-guide/finishes/aniline-dyes If the wood is dense and smooth, like maple, pigment particles find few places to rest. Basic dyes comprise: Amino groups / Alkylamino groups (as their auxochromes) A few examples of basic dyes are: Methylene blue; Crystal violet; Basic fuchsin safranin; Further, an example of basic dye which has amino groups as their auxochrome is Basic Blue 9 which is very popular dye and has great usage value. It has long been believed that aniline dyes, ... and there are many examples in which their indiscriminate use produced a riot of clashing colors. 2 words related to aniline dye: dye, dyestuff. Examples of simultaneous staining with anionic dyes include Mann's method with eosin Y and Aniline Blue, Van Gieson's method with Acid Fuchsine and Picric Acid, and the related picro‐sirius method with Picric Acid and Sirius Red F3B . All colors achieved using strictly all aniline dyes will fade, whether it is on fabric, leather, or wood. Figure 2. For use on new wood surfaces. This quickly spawned a new area of research into triphenylmethane dyes from which the second aniline based dye, Magenta (fuchsin), was discovered. Aniline definition, a colorless, oily, slightly water-soluble liquid, C6H5NH2, usually derived from nitrobenzene by reduction: used chiefly in the synthesis of dyes and drugs. Generic structure for azo dyes, where Ar1 and Ar2 are aromatic systems. Most manufacturers use dyes more frequently in the pre-staining or NGR application in the finishing processes.
