Mercaptane  – Thiole

Mercaptan is a now obsolete name for the thioalcohols. According to today’s nomenclature rules, the mercaptans are called thiols. Their name comes from their ability to bind mercury(II) ions (lat. mercurium captans = capturing mercury).

Mercaptans is a highly flammable liquid that emits toxic fumes. It is slightly lighter than water but not miscible with it. Typical of mercaptans is its distinctly unpleasant odor.

Mercaptans: Dangers

Mercaptan tends to ignite suddenly. It must be transported in closed containers. If the pressure rises, there is a risk of explosion. An explosive mixture can also form with warm ambient air.

Mercaptan vapors can be invisible and are heavier than air. They spread along the ground and can enter sewers and basements.

Toxic vapors are also produced in fires. Fires must not be extinguished with water.
