Walther Schrauth

Walther Schrauth , sometimes Walter, (born February 20, 1881 in Magdeburg , † May 1, 1939 in Rodleben near Dessau ) was a German chemist and entrepreneur.

Life

Schrauth, the son of the businessman and soap manufacturer (Müller & Kalkow) Hermann Emil Schrauth (1851–1904) and Marie Emilie Regine Schrauth, b. Müller (1853–1933), studied chemistry and physics in Munich and Berlin after graduating from high school at the monastery of our dear women in Magdeburg in 1902 and received his doctorate in Berlin in 1906 (on the behavior of some diketopiperazines against alkali . Presentation of tyrosyltyrosine and tyrosylglycine). He was briefly at the material testing office , was a teaching assistant at the Chemical Institute of the University of Berlin and studied medicine up to the Physikum 1914. After his habilitation in 1915, he was a private lecturer in Berlin when he was commissioned by the Reichsmarineamt in 1916took over the construction and management of a plant for tetralin production in Rodleben near Roßlau for the Tetralin plants (later Deutsche Hydrierwerke). In 1922 he became a board member of Riedel AG and in 1927 chairman of the board of Deutsche Hydrierwerke AG (Dehydag) in Rodleben. In 1924 he became associate professor at the University of Berlin and in 1933 honorary professor at the TH Berlin-Charlottenburg .

Schrauth initially developed organic compounds containing mercury with Walter Julius Viktor Schoeller , with the aim of developing a remedy for syphilis . This resulted in disinfecting soaps . The soap factory Müller & Kalkow in Magdeburg produced these soaps for Bayer Leverkusen . There the packaging and distribution took place under the name Afridol. The patents were taken over by the Elberfelder Farbwerke and were also used in pest control ( wood protection ) and in medicine as diuretics .

Later in his company he developed methods for the hydrogenation of coal tar chemical compounds and the catalytic high-pressure hydrogenation of fatty acid esters and fatty acids to fatty alcohols (developed with O. Schenk, K. Stickdorn) and used them to produce fatty alcohol sulfates as surfactants for detergents , first used in 1932 as Fewa from the Böhme company (later Henkel ) by Heinrich Gottlob Bertsch . During the development he was advised by the grease hardening expert Wilhelm Normann .

He also did research on lignin , plasticizers , adipic acid, and sperm oil .

Walther Schrauth died in 1939 at the age of 58 and was buried in the Dahlem Forest Cemetery in Berlin. The grave has not been preserved.
