William H. Perkin

The first synthetic dye is developed by William H. Perkin (English) he accidentally creates a mauve dye from the impure aniline in coal tar. 

A few years later, William H. Perkin,based on the amazing but erroneous idea, attempted a potassium dichromate-mediated oxidative dimerization of A-allyltoluidine (C10H13N) to produce quinine. Since A-allyltoluidine is structurally nothing like half a quinine molecule, this attempt was unsuccessful and futile. The entire idea was based on a newly reported empirical formula of quinine [2C10H13N -l- 30 = C20H24N2O2 + H2O] and although the arithmetic was suggestive, there was no chance that Perkin could have obtained quinine. 

In 1856 William H. Perkins at the age of eighteen synthesized for the first time the mauve color mauveine [6373-224] by oxidizing aniline containing toluidine with chromic acid. This event ushered in an era of colored synthetic chemistry which continues into the 1990s. Many new organic structures have been discovered and introduced as commercial oiganic pigments.

Harold attended the Central Board School in Manchester and, at the age of seventeen, was awarded a Manchester Corporation Scholarship. In 1894, he entered Owens College of the federal Victoria University, Manchester, and, three years later, graduated with a B. Sc. with First Class Honours in Chemistry. He was awarded the Levinstein Exhibition fellowship, proceeded to conduct his first researches in organic chemistry under Professor William H, Perkin, Jnr., and received his M. Sc. degree from the Victoria University in 1900, the year of his first publication. 

It is worthwhile to visit early views about naturally occurring organic ring compounds. The first cyclic molecule to have its structure established was benzene in 1865 and, for a brief period, six-membered rings were thought to be the only possibility. During the 1880s William H. Perkin, Jr. (1860-1929), the son of William H. Perkin (1838-1907) who discovered the dye mauve, and a student of Baeyer, established the existence of three-, four-, and five-membered carbocycles. Baeyer strain in cyclopropane causes it to react with HCl as if it were an alkene rather than an alkane. 

Perkin Medal by the American Chemical Society in 1992. She was the first woman to win this award. Tradition dictated that the winner wear a mauve-colored tie (in honor of William H. Perkin, who synthesized mauve, the first dye derived from coal tar). In keeping with the spirit, if not the letter, of this tradition, Flanigen purchased a spectacular mauve-colored dress for the occasion of her award. 

Anthracene was first discovered in coal tar by Jean B.A. Dumas and Auguste Laurent in 1832. The importance of anthracene for industrial aromatic chemistry began with the synthesis of the dyestuff alizarin by Carl Graebe and Carl Th. Liebermann, as well as by William H. Perkin in 1868, replacing the natural dye produced from madder. Anthraquinone dyestuffs have remained the most important class of dyes, alongside azo-dyes, since the beginning of the chemistry of synthetic dyestuffs. 

Synthetic dye (William H. Perkin) British chemist Perkin produces the first synthetic dye. The color is mauve, which triggers a mauve fashion revolution.

Perkin, W. H. J. Chem. Soc. 1868, 21, 53. William Henry Perkin (1838—1907), bom in London, England, studied under Hofmann at the Royal College of Chemistry. In an attempt to synthesize quinine in his home laboratory in 1856, Perkin synthesized mauve, the purple dye. He then started a factory to manufacture mauve and later other dyes including alizarin. Perkin was the first person to show that organic chemistry was not just mere intellectual curiosity but could be profitable, which catapulted the discipline into a higher level. In addition, Perkin was also an exceptionally talented pianist.
