Any one of series of compounds having an -SH radical attached to a carbon atom, also considered as hydrosulphides of alcohol radicals, in composition resembling the alcohols, but containing sulphur in place of oxygen, and hence called also the sulphur alcohols. In general, they are colorless liquids having a strong, repulsive, garlic odor. The name is specifically applied to ethyl mercaptan, C2H5SH. So called from its avidity for mercury, and other metals.
An organic chemical compound that has a sulfur like odor that is added to natural gas before distribution to the consumer, to give it a distinct, unpleasant odor (smells like rotten eggs). This serves as a safety device by allowing it to be detected in the atmosphere, in cases where leaks occur.
Unpleasant, sulphur-like rubbery smell that may be present in very old white wines.
Odorant added to natural gas so it can be smelled. Without it, natural gas is odorless.
A chemical added to natural gas that makes it smell like rotten eggs so people will know if natural gas is leaking.
unpleasant fetid odour reminiscant of rotten eggs
a substance added to natural gas to create an odor for safety detection.
a sour, unpleasant rubbery smell indicating deterioration in wines. It can be attributed to breakdown of sulfur containing compounds used for wine preservation.
A hydrogen sulfide contaminant, which gives wine a variety of unpleasant odors such as manure, rotten meat, or rotten eggs. A by-product of sterilizing wine barrels with too much burning sulfur.
A sulfur-containing compound that reacts with the chloride in PVC to reduce decomposition. (Also called thiols.)
Odorant added to natural gas by the LDC
form of alcohol in which oxygen is replaced by sulfur. Has a strong and disagreeable taste and smell.
A highly concentrated odorant that is injected into natural gas before it enters a utilities distribution system. Mercaptan gives off a foul smell, reminiscent of rotten eggs.
An odorant added to natural gas for safety detection purposes.
An organic chemical compound having a distinctive odor used for odorization of gas streams.
This is an unpleasant rubbery smell caused by the breakdown of the sulphur that is preserving the wine.
A chemical compound injected into natural gas pipelines as a safety measure to give natural gas a distinctive odor and help detect leaks.
Any of various compounds that contain a thiol functional group. Mercaptans are found in crude oil and are removed from most petroleum products by refining. However, they may be added to natural gas and liquefied petroleum gas in very low concentrations to give a distinctive warning odor.
