Aniline in the context of "August Wilhelm von Hofmann"

Indigo dye is an organic compound with a distinctive blue color. Indigo is a natural dye obtained from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were once common throughout the world. It is now produced via chemical routes from aniline. Blue colorants are rare. Since indigo is insoluble, it is also referred to as a pigment (C.I. Pigment Blue 66, C.I.).

Most indigo dye produced today is synthetic, constituting around 80,000 tonnes each year, as of 2023. It is most commonly associated with the production of denim cloth and blue jeans, where its properties allow for effects such as stone washing and acid washing to be applied quickly.

Magenta is a purplish red color. On color wheels of the RGB and CMYK color models, it is located directly midway between blue and red. It is one of the 4 colors of substractive ink used in color printing by most color printers, also known as CMYK along with yellow, cyan, and black to make all the other colors and hues. The tone of magenta used in printing, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to rose.

Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it fuchsine. It was renamed to celebrate the French-Sardinian victory under French Emperor Napoleon III at the Battle of Magenta against the larger army of the Austrian Empire on 4 June 1859 near the Italian town of Magenta, at the time in Austria. This battle was decisive in liberating Italy from Austrian domination.

The Handschiegl color process (U.S. patent 1,303,836, U.S. patent 1,303,837, App: Nov 20, 1916, Iss: May 13, 1919) produced motion picture film prints with color artificially added to selected areas of the image. Aniline dyes were applied to a black-and-white print using gelatin imbibition matrices.

BASF SE (German pronunciation: [beːaːɛsˈʔɛf] ), an initialism of its original name Badische Anilin- und Sodafabrik (German for 'Baden Aniline and Soda Factory'), is a German multinational company and the largest chemical producer in the world. Its headquarters is located in Ludwigshafen, Germany.

BASF comprises subsidiaries and joint ventures in more than 80 countries, operating six integrated production sites and 390 other production sites across Europe, Asia, Australia, the Americas and Africa. BASF has customers in over 190 countries and supplies products to a wide variety of industries. Despite its size and global presence, BASF has received relatively little public attention since it abandoned the manufacture and sale of BASF-branded consumer electronics products in the 1990s.

Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to previous wars. Sulfanilamide is rarely if ever used systemically due to toxicity and because more effective sulfonamides are available for this purpose. Modern antibiotics have supplanted sulfanilamide on the battlefield; however, sulfanilamide remains in use today in the form of topical preparations, primarily for treatment of vaginal yeast infections such as vulvovaginitis caused by Candida albicans.

The term "sulfanilamides" is also sometimes used to describe a family of molecules containing these functional groups. Examples include:

Johann Friedrich Weskott (8 October 1821 – 4 October 1876) was a German master dyer and industrialist who co-founded the dyestuffs firm Friedr. Bayer et comp. in 1863 with Friedrich Bayer. The partnership, initially focused on synthetic coal-tar (aniline) dyes such as fuchsine, grew into the company later known as Bayer AG.

Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.

If, as is usually the case, the volatiles are not miscible with water, they will spontaneously form a distinct phase after condensation, allowing them to be separated by decantation or with a separatory funnel.
