Eugène-Melchior Péligot (24 March 1811 – 15 April 1890), also known as Eugène Péligot, was a French chemist who isolated the first sample of uranium metal in 1841. [2]
Péligot proved that the black powder of Martin Heinrich Klaproth was not a pure metal (it was an oxide of uranium, known in chemistry as UO2). He then succeeded in producing pure uranium metal by reducing uranium tetrachloride (UCl4) with potassium metal. [3] Today better methods have been found. [4]
Péligot was a professor of analytical chemistry at the Institut National Agronomique. He collaborated with Jean-Baptiste Dumas, and together they discovered the methyl radical during experiments on wood spirit ( methanol). The terminology " methyl alcohol" was created by both chemists from "wood wine". They also prepared the gaseous dimethyl ether, and many esters. In 1838, they successfully transformed camphor into p-cymene using phosphorus pentoxide.
In 1844 he synthesized chromium(II) acetate, [5] [6] which was much later recognized (by F. Albert Cotton in 1964) to be the first chemical compound which contains a quadruple bond. [7]
