EXTRACTION AND PRESENTATION of TERT-DODECANETHIOL:
Tert-Dodecanethiol can be prepared from tetrapropylene using hydrogen sulfide.

COMPOSITION of TERT-DODECANETHIOL:
In technical terms, Tert-Dodecanethiol refers to a mixture of isomeric alkyl thiols (common name: alkyl mercaptans) in which the mercaptan groups are each substituted with an alkyl group containing 12 carbon atoms.

The carbon atoms supporting the mercaptan group are predominantly tertiary carbon atoms, meaning they are bonded to three other carbon atoms in addition to the mercaptan group.
However, Tert-Dodecanethiol always contains a certain proportion of secondary mercaptans, in which the carbon atom supporting the mercaptan group is bonded to only two other carbon atoms and one hydrogen atom.

Tert-Dodecanethiol also usually contains a smaller proportion, typically up to 20% by weight, of shorter- or longer-chain alkyl groups, such as alkyl groups with 10, 11, 13, and/or 14 carbon atoms.
Tert-Dodecanethiol therefore has the idealized semi-structural formula C12H25-SH, although depending on the content of alkyl groups with more or fewer carbon atoms, there is a certain deviation from this idealized stoichiometric composition.
