Thiols

Mercaptans (thiols) are organic compounds containing one or more sulfide (-SH) groups in the molecule. The term was proposed in 1811 by Louis François Bijerinck. M. are not used as medicines, but are used in food. industry, as a finishing agent for cotton and wool fabrics, derivatives of carbon disulfide in quality. fungicides and bacteriolytics (20 mg per 1 liter of water), as well as technical. M. in quality inorganic reducing agent, sulfur-producing acid, initiating agent for rubber vulcanization, due to their choleretic effect.

M. - colorless, highly volatile liquids with a garlicky odor (due to the presence of the mercaptile group -SH Mercaptans have been known since ancient times and were discovered more than one and a half thousand years ago; by accident, when plant residues were boiled into a toxic substance, goat hair was released during evaporation in a closed vessel. This alchemists described the substance for the first time. Now they use different areas of chemistry to obtain mercaptans. They are the main products of cracking petroleum products and can be isolated from a mixture of aromatic hydrocarbons due to the hydrogenation of aromatic sulfides, especially if their content in the raw material is more than 1%, and the yield during cracking is more than 5%.
