Albrecht Haack

from Wikipedia, the free encyclopedia

Albrecht Haack (born December 6, 1898 in Südende , † September 22, 1976 in Munich ) was a German chemist .

1919-1924 Chemistry and Natural Sciences Haack studied at the University of Erlangen with a diploma in 1924. There he was in 1926 Otto Fischer (and Anton Vilsmeier ) PhD . From 1928 to 1941 he was a company chemist at the milk center in Karlsruhe. From 1941 to 1945 he did military service and then worked for the tax authorities in Erlangen and Nuremberg and in other positions (but which had nothing to do with chemistry). In 1963 he retired.

The Vilsmeier-Haack reaction for the formylation of aromatics with formamides and phosphorus oxychloride , which he discovered together with Anton Vilsmeier , bears his name . According to Vilsmeier, however, this was only the elucidation of the synthesis method previously found in his own dissertation.
