Nevil Vincent SidgwickDied 15 Mar 1952 at age 78 (born 8 May 1873). English chemist who contributed to the understanding of chemical bonding, especially in coordination compounds. He worked on kinetics (studying the rates of isomerisation of triphenylmethane dye intermediates and the hydration of carboxylic anhydrides), thermodynamics (investigating phase equilibria and the solubility of organic acids and bases), as well as investigating the colour of copper complexes. During WW I, he set to work on a process for the production of acetone (propanone) from ethanol and other wartime projects, such as the production of phenol from benzene. His book, The Electronic Theory of Valency (1927) was a culmination of many years' interest in the nature of covalent and dative bonds. |
