Carl Krauch senior (born April 9, 1853 in Cleebronn ; † June 8, 1934 in Cappel near Öhringen ) was a German chemist.

Life

After an apprenticeship as a pharmacist , Krauch studied chemistry and pharmacy from 1874 at the University of Erlangen as a private assistant to the professor there, Albert Hilger . In the summer of 1877 he successfully completed his studies with an oral doctoral examination in chemistry, botany and agricultural chemistry and a doctoral thesis on the subject of contributions to the knowledge of the unformed ferments in plants .

He then worked for five years as an assistant at an agricultural research station in Münster . On November 1, 1882, he switched to the Merck company as a control chemist .

He tested reagents with other control chemists in the laboratory and compared them. He came to the conclusion that many discrepancies in the tests were due to the impurity of the fabrics. In 1888 he brought out the first standard analytical work with the title Testing chemical reagents for purity , in which instructions for purity testing could be found. On the occasion of the 100th anniversary of this first-time standardization of analytical methods, Merck founded the Heinrich Emanuel Merck Prize for Analytics.

From 1890 was Krauch head of the department responsible for lactic acid - and butyric -Fabrication by fermentation of whey was responsible. In 1919 he retired from professional life.

His son Carl Krauch and his grandson Carl Heinrich Krauch also became chemists.
