Life

D'Ans studied at the TH Darmstadt from 1899 until his doctorate in 1905, was an assistant to Jacobus Henricus van 't Hoff in Berlin for a year and then went back to Darmstadt, where he taught analytical chemistry and completed his habilitation in 1909 ("Investigations on calcium alkali sulfates") ) and was a private lecturer . From 1914 he headed the laboratory in the paper and pulp mill in Cosel-Oderhafen and from 1919 the scientific department of the Auer Society , of which he became a board member in 1923. From 1938 to 1947 he was director of the Kali Research Institute in Berlin, which he had advised since 1930. From 1945 he was a full professor and director of the Institute for Inorganic Chemistry at the TU Berlin , whose rector he was in 1947/48. From 1951 until his retirement in 1953 he was professor of technical and general chemistry there.

He dealt with solution equilibria, especially of potash salts, including graphic methods for determining metastable equilibria with application to their processing. Later he dealt with peroxides , including a simple method of representing organic peroxides. With Ellen Lax , he was the editor of the paperback for chemists and physicists , also known as "D'Ans-Lax" for short.

In 1949 he was briefly a full member of the German Academy of Sciences in Berlin .

Jean D'Ans died in Berlin in 1969 at the age of 87. His grave is in the forest cemetery in Zehlendorf .

The rare, initially nameless mineral D'Ansit was discovered in 1909 and named in his honor in 1958 after its synthetic production had succeeded.
