词源

Etymology tree German Mercaptanbor. English mercaptan Borrowed from German Mercaptan, from Danish mercaptan; coined by organic chemist William Christopher Zeise in 1832 from mer(curius) (“mercury”) + captan(s) (“capturing”), because the thiolate group bonds very strongly with mercury compounds.
