Arthur George Green

from Wikipedia, the free encyclopedia

Arthur George Green (* 1864 in London ; † September 12, 1941 ibid) was a British chemist ( dye chemistry ).

Life

Green was the son of an architect and studied science at University College London from 1880 . After graduating in 1885, he went into industry and developed dyes there.

First he was at Atlas Works in Hackney Wick near London, where in 1887 he developed the yellow dye primulin and from it a red dye for cotton. When his company did not take advantage of this, he went to the Clayton Aniline Company in Manchester in 1894, where, in addition to utilizing his old developments, he developed stilbene dyes, azo dyes and sulfur dyes .

In 1901 he became a professor of dye chemistry at the University of Leeds . In 1916 he also took over the management of the Dyestuff Research Laboratory of the College of Technology in Manchester and in 1918 became research director of the Levinstein company, which he remained until it was taken over by the British Dyestuff Corporation in 1923. He had a private laboratory and was an advisor to ICI from 1935 onwards .

In 1904, together with Arthur George Perkin, he refuted Wilhelm Ostwald's hypothesis that the color change in phenolphthalein was due to dissociation. Instead, they suggested an aromatic structure for the colorless form and a quinoid structure for the colored one .

He further developed the coloring with aniline black by replacing the fiber-damaging chlorates with air oxidation (Greensches Schwarz). Around 1922 he developed water-soluble dyes for cellulose acetate , called ionamines.
