Jacob Böeseken

Jacob Böeseken (born August 20, 1868 in Rotterdam , † May 16, 1949 in Delft ) was a Dutch chemist and professor at the Technical University of Delft .

Life

Jacob Böeseken was born in Rotterdam in 1868 as the son of Antonij Böeseken and Johanna Glazener. He married Maria Valk on August 17, 1899. With this he had two sons and a daughter.

After studying chemical technology at the Polytechnic School in Delft (1887-1893), Böeseken was assistant at the national agricultural research station in Groningen . In 1894 he assisted Arnold F. Holleman at the chemical laboratory at the University of Groningen . Since he could not do his doctorate as a chemical technician at a Dutch university, he moved to the University of Basel on May 11, 1897 , where he completed his doctorate with the topic: About the products of the action of primary amines on dinitrosacyls . After a time as a lecturer at the Hogereburgerschool and at the grammar school in Assen , he was appointed as a lecturer at the University of Groningen in 1906. The following year he succeeded Sebastiaan Hoogewerff as Professor of Organic Chemistry at the Technical University of Delft. His inaugural lecture on October 16, 1907 was entitled: "Interactions between Scientific Research and Organic-Chemical Technology". He held this professorship until 1938. He said goodbye on June 24, 1938 with his lecture: “Organic Chemistry in the Last Quarter of a Century” and went into retirement.

Böeseken died in Delft in 1949.

Act

As a lecturer in organic chemistry, Böeseken mainly focused on biochemical issues. He realized that the development of organic chemistry required the methods of physical chemistry in order to deepen the understanding of the structure and behavior of organic molecules. Important contributions from Böeseken concerned the configuration of organic compounds using the example of boric acid complexes of polyhydroxy compounds . The Böeseken reaction named after him comes from this area : an analytical method for the determination of cis -1,2-diols. For his services, he was appointed a member of the Royal Dutch Academy of Sciences in 1915 . From 1917 on, Böeseken and his academic students investigated 5- and 6-membered carbon rings . His other work includes determining the constitution of unsaturated compounds such as eleostearic acid in fats .
