- n. A colorless, oily, poisonous benzene derivative, C6H5NH2, used in the manufacture of rubber, dyes, resins, pharmaceuticals, and varnishes.
- adj. Derived from aniline.
Century Dictionary and Cyclopedia
- n. Amidobenzol, C6H5NH2, a substance which furnishes a number of brilliant dyes. It was discovered in 1826 by Unverdorben, as a product of the distillation of indigo, and called by him crystallin. It did not acquire commercial importance until 1856, when the purple dye mauve was prepared from it by Perkin. It is found in small quantities in coal-tar, but the aniline of commerce is obtained from benzol, another product of coal-tar, consisting of hydrogen and carbon, C6H6. Benzol when acted on by nitric acid produces nitrobenzol; and this latter substance when treated with nascent hydrogen, usually generated by the action of acetic acid upon iron filings or scraps, produces aniline, which is an oily liquid, colorless when pure, somewhat heavier than water, having a peculiar vinous smell and a burning taste. It is a strong base, and yields well-characterized salts. When acted on by arsenic acid, potassium bichromate, stannic chlorid, etc., aniline produces a great variety of compounds of very beautiful colors, known by the names of aniline purple, aniline green, violet, magenta, etc. Also called
- Pertaining to or derived from aniline: as, aniline colors.
- n. organic chemistry The simplest aromatic amine, C6H5NH2, synthesized by the reduction of nitrobenzene; it is a colourless oily basic poisonous liquid used in the manufacture of dyes and pharmaceuticals.
GNU Webster's 1913
- n. (Chem.) An organic base belonging to the phenylamines. It may be regarded as ammonia in which one hydrogen atom has been replaced by the radical phenyl. It is a colorless, oily liquid, originally obtained from indigo by distillation, but now largely manufactured from coal tar or nitrobenzene as a base from which many brilliant dyes are made.
- adj. Made from, or of the nature of, aniline.
- n. oily poisonous liquid amine obtained from nitrobenzene and used to make dyes and plastics and medicines
- German Anilin (coined by German Chemist Carl Julius Fritzsche). From Portuguese anil ("indigo") + -in ("-ine (organic compounds)"). (Wiktionary)
- anil + -ine2. (American Heritage® Dictionary of the English Language, Fourth Edition)
“A.W. 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.”
“FURFURAL ANILINE: A resin formed from furfural and aniline, which is a cyclic amine derived from benzene, and is nowadays obtained from coal.”
“The resulting compound is known as aniline, a liquid boiling at 182°.”
“The discovery of the so-called aniline dyes has greatly increased the variety of colors available.”
“The chief poisonous dyes are the red and yellow coralline, substances derived from that series of chemical bodies which have been obtained of late years from coal tar, and commonly known as the aniline series.”
“It is well known that in coal-tar is found a series of ammonia-like bases, aniline or amido-benzol, toluidine or amido-toluol, and xylidine or amido-xylol, which are utilized practically in the manufacture of the so-called aniline dye-colors.”
“Fritsche in the same year by the distillation of indigo with caustic potash developed a product which he also called aniline, the name being derived from the Portuguese word anil, meaning indigo.”
“From benzoline, again, we get a liquid called aniline, from which are made so many of our beautiful dyes - mauve, magenta, and violet; and what is still more curious, the bitter almonds, pear - drops, and many other sweets which children like to well, are actually flavoured by essences which come out of coal-tar.”
“In Germany a substitute has been found in aniline, which is so cheap that within a measurable distance of time no indigo whatever will be bought.”
“Some progress has been made in this direction, but so far the main results are certain degradation-products such as aniline dyes derived from coal tar; salicylic acid; essences of fruits; etc. Still these and many other discoveries of the same nature do not prove that the laboratory of man can compete with the laboratory of the living plant cell.”
