释义
van’t Hoff, Jacobus Henricus (1852–1911)

Chemical Engineering
  • A Dutch professor of chemistry in Amsterdam, and then Leipzig and Berlin, who had studied in Holland, France, and Bonn. He began his research at twenty years of age and his simple theory that the four valency bonds of a carbon atom are directed to the four corners of a tetrahedron explained asymmetrical carbon compounds and established stereochemistry in 1874. In 1886 he explained osmosis, and showed the connection between osmotic and gas pressures, which led to the Arrhenius’ theory of electrolytic dissociation. He received the first Nobel Prize in Chemistry in 1901.


Geology and Earth Sciences
  • and winner of the 1901 Nobel Prize for chemistry for his work on the relationship between osmotic pressure and vapour pressure, van’t Hoff was professor of chemistry, mineralogy, and geology at Amsterdam University and later an honorary professor at the Prussian Academy of Sciences. His work on phase equilibria (see phase diagram), involving six components of sea water at a range of temperatures, contributed much to the study of sedimentary processes and in particular provided a theoretical basis for understanding the formation of salt deposits.
