ethanethiol technical , auch: ethyl mercaptan technical

Ethanethiol was originally reported by Zeise in 1834.

Ethanethiol is more volatile than ethanol due to a diminished ability to engage in hydrogen bonding.

At these concentrations, ethanethiol is not harmful.

Ethanethiol is prepared by the reaction of ethylene with hydrogen sulfide over a catalyst.

Ethanethiol is a valued reagent in organic synthesis.

In the underground mining industry, ethanethiol or ethyl mercaptan is referred to as "stench gas".

Ethanethiol can be oxidized to ethyl sulfonic acid, using strong oxidizing agents.

Reaction of 8c with methanol and ethanethiol gives an iminoester and an iminothioester respectively.

Ethanethiol is toxic.

For example, the ethyl mercaptan (ethanethiol) has the formula CHSH.

Cleave of the O-methyl ether with sodium Ethanethiol affords proxorphan (9).

Ethanethiol can also be prepared by a halide displacement reaction, where ethyl halide is reacted with aqueous sodium bisulfide.

Captan is also the common name for ethanethiol or ethyl mercaptan, used as an odorant for natural gas and liquid propane delivery to help identify leaks.

Similar systems are used in mines, where ampoules of ethanethiol are broken in front of ventilation fans to warn of gas in the mines.

The initial decomposition gives principally ethyl radicals and ethylthiyl radicals; a second step which yields ethylene and ethanethiol may account for up to 20% of the primary process.

The second order rate constants for the reaction of ethanethiol with a number of conjugated nuclear-substituted styryl ketones and related Mannich bases in 50% aqueous acetonitrile was undertaken.

Ethanethiol is intentionally added to butane and propane (see: LPG) to impart an easily noticed smell to these normally odorless fuels that pose the threat of fire, explosion, and asphyxiation.

A very useful application of the Arndt-Eistert homologation forms the homologated aldehyde by either trapping the ketene with N-methyl aniline and reducing with lithium aluminum hydride, or trapping the ketene with ethanethiol and reducing with Raney nickel.
