The readings were aimed at tracing Acrolein, Acrylonitrile, Methyl Mercaptan
and Benzene, as part of air quality monitoring activities undertaken by the department.
Chemical Safety Board, comments on the findings of the board's investigation into the release of methyl mercaptan
at the DuPont Plant in La Porte, Texas, that killed four workers.
In particular, the document limits oil content of hydrogen sulfide, methyl mercaptan
, ethyl mercaptan
and other hazardous chemical compounds.
Chemical Sampling Information: Butyl mercaptan
Because natural gas is colourless and odourless, companies often add Mercaptan
or methanethiol, which has a pungent smell likened to rotten eggs, to make it easier to detect.
There were also reports the smell was due to a leak of an odorant called Mercaptan
, which is added to gas (which has no scent) to help people realise when a leak happens.
The scent being used for the scratch-and-sniff contains Mercaptan
, the same odorant that is added to natural gas to make it noticeable.
The most common type is one that adds a mercaptan
liquid into natural gas distribution systems so that leaks can be readily detected.
15 2014, veteran operator Crystal Rae Wise opened a faulty valve on a pipe carrying methyl mercaptan
, a chemical used to manufacture DuPont's popular insecticide called Lannate.
(1) If the redox potential of a must is not increased during [H.sup.2]S formation (aerated must), the [H.sup.2]S can react with other compounds such as ethanol and sulfur-containing amino acids to form mercaptans
(most notably, methyl mercaptan
