Wolfgang Dähne

from Wikipedia, the free encyclopedia

Wolfgang Dähne (born March 17, 1932 in Hamm ; † September 28, 2010 ) was a German chemist. In 1962 he and Rudolf Hoppe succeeded in establishing a binary noble gas compound for the first time, at the same time as a US group .

Life

As the son of the notary and lawyer Paul Dähne and his wife Lotte Unterhinninghofen, Wolfgang Dähne completed the Protestant elementary school and the state grammar school in Hamm until 1944, when the grammar school was destroyed by a bomb attack. At the age of 12 he lost his father, who fell as a lieutenant colonel in the reserve in 1944 in Lithuania. After a bomb attack, he was evacuated to Bergede . This enabled him to attend the Archigymnasium Soest from the spring of 1946 , where he passed the Abitur exam in March 1952.

From mid-1952 he studied chemistry at the Westphalian Wilhelms University . In May 1958 he passed the examination to become a qualified chemist with the work investigations on lithium hexafluorometallates Li 2 MnF 6 and Li 2 ZrF 6 . The instructions for this work were provided by Wilhelm Klemm as head of the Inorganic Chemical Institute. Klemm also gave him the topic of the dissertation on fluorometallates of lithium and sodium and manganese tetrafluoride , with which he obtained his doctorate on February 16, 1962 under the dean of Ewald Wicke . In his dissertation, he examined and analyzed the properties of fluoromanganates of lithium (LiMnF 3 , LiMnF 4 , LiMnF 5 ) and of lithium and sodium trifluorocuprates (II) (LiCuF 3 , NaCuF 3 ).

He also investigated the compounds Na 2 SiF 6 and Li 2 SiF 6 and created images of the crystal structure of Li 2 SiF 6 using X-ray imaging . He also analyzed this compound on single crystals at higher temperatures. Then he succeeded with Rudolf Hoppe in 1962 in synthesizing the binary noble gas compound of xenon with fluorine as xenon difluoride (XeF 2 ). In 1962 he started working for Degussa AG. There he researched ceramics for several years before taking over the management of a factory in Limoges .

From 1972 to 1992 he headed the processing and manufacturing operations for silver, gold and platinum metals at the Wolfgang metal works. During this time, too, he represented the company's precious metal chemistry in public and in publications. He retired in March 1993.
