English edit
Etymology edit
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.
Pronunciation edit
Noun edit
mercaptan (plural mercaptans)
- (chemistry) Any of a class of organic compounds of sulphur, ( R1.S.R2 ); they tend to be foul-smelling. When R2 is a hydrogen atom, they are termed thiols or thioalcohols.
- 2022 April 25, AlfredCamera, “Spotting Gas Leak Symptoms and Staying Safe”, in Home Security Expert[1]:
- Though this might come as a surprise, gas actually has no odor; gas companies are obligated to odorize it to make it safer for use in homes.
Mercaptan, a harmless chemical, is added to create the distinct smell in both natural gas (methane) and liquid petroleum gas (propane, butane).
