description Roger Adams Overview
Roger Adams (1889–1971) was an American organic chemist who spent most of his career at the University of Illinois at Urbana-Champaign. He is best known for developing Adams' catalyst, a platinum oxide (PtO₂) reagent widely used for catalytic hydrogenation of organic compounds. Adams also contributed to the structural determination of tetrahydrocannabinol (THC) from cannabis and of gossypol from cottonseed oil. He served as chairman of the chemistry department at Illinois from 1926 to 1954.
help Roger Adams FAQ
What is Adams' catalyst and what is it used for?
Adams' catalyst is a chemical reagent consisting of platinum oxide (PtO₂). It is widely used in organic chemistry laboratories for the catalytic hydrogenation of various organic compounds.
Where did Roger Adams spend his academic career?
Roger Adams spent the vast majority of his highly influential career at the University of Illinois at Urbana-Champaign. He helped build the university's chemistry department into one of the top programs in the United States.
What role did Roger Adams play in 20th-century American chemistry?
Beyond developing his famous catalyst, Adams was a monumental figure who mentored hundreds of Ph.D. chemists. He also played a crucial advisory role to the United States government on chemical warfare and synthetic rubber during World War II.
How does Adams' catalyst function in a chemical reaction?
The platinum oxide powder is mixed with a liquid solution of the target compound and exposed to hydrogen gas. During the reaction, the oxide is reduced to active finely divided platinum metal, which acts as the actual catalyst to add hydrogen to the molecule.
