Friedrich Krafft

Friedrich Krafft (February 21, 1852 in Bonn – June 3, 1923 in Heidelberg) was a German chemist.[1] He studied with Friedrich August Kekulé von Stradonitz, Rudolf Clausius and Gerhard vom Rath.

Krafft, c. 1900

In colloidal chemistry, the Krafft temperature is named after him. In organic chemistry, the Krafft degradation reaction is named after him.[2] This reaction is a conversion of a carboxylic acid, typically of high molecular weight, into the next lower homolog. He also established the boiling point of noble metals and synthesised aromatic compounds containing selenium and tellurium.
