1-Propanethiol Chemical Properties,Uses,Production

Chemical Properties

clear colourless liquid


ChEBI: An alkanethiol that is propane substituted by a thiol group at position 1.

General Description

A colorless liquid with a strong, offensive odor. Moderately toxic. Flash point below 0°F. Less dense than water and slightly soluble in water. Hence floats on water. Used as a chemical intermediate and a herbicide.

Air & Water Reactions

Highly flammable. Vapors explosive when exposed to heat, flame or sparks. Slightly soluble in water.

Reactivity Profile

1-Propanethiol emits toxic fumes of oxides of sulfur when heated to decomposition. Reacts violently on contact with calcium hypochlorite [Chem. Eng. News, 1973, 51(26), p. 14].

Health Hazard

Inhalation causes muscular weakness, convulsions, and respiratory paralysis; high concentrations may cause pulmonary irritation. Contact with liquid causes irritation of eyes and skin. Ingestion causes irritation of mouth and stomach.

Fire Hazard

Special Hazards of Combustion Products: Toxic sulfur dioxide is generated.

Purification Methods

Purify the thiol by dissolving it in aqueous 20% NaOH, extracting with a small amount of *benzene and steam distilling until clear. After cooling, the solution is acidified slightly with 15% H2SO4, and the thiol is distilled out, dried with anhydrous CaSO4 or CaCl2, and fractionally distilled under nitrogen. [Mathias & Filho J Phys Chem 62 1427 1958.] Also purify it by liberating the mercaptan by adding dilute HCl to the residue remaining after steam distilling. After direct distillation from the flask, and separation of the water, the mercaptan is dried (Na2SO4) and distilled under nitrogen. [Beilstein 1 IV 1449.]
