75-08-1 Usage

General Description

A clear colorless low-boiling liquid (boiling point 97°F) with an overpowering, garlic-like/skunk-like odor. Flash point -55°F. Less dense than water and very slightly soluble in water. Vapors are heavier than air. Vapors may irritate nose and throat. May be toxic if swallowed, by inhalation or by contact. Added to natural gas as an odorant. Used as a stabilizer for adhesives.

Reactivity Profile

Ethanethiol reacts violently with calcium hypochlorite, May react vigorously with other oxidizing reagents. On contact with strong acids or when heated to decomposition Ethanethiol emits highly toxic fumes of sulfur oxides [Sax, 9th ed., 1996, p. 1575].

Chemical Properties

colourless liquid with a penetrating,

Purification Methods

Dissolve the thiol in aqueous 20% NaOH, extract it with a small amount of *benzene and then steam distil until clear. After cooling, the alkaline solution is acidified slightly with 15% H2SO4 and the thiol is distilled off, dried with CaSO4, CaCl2 or 4A molecular sieves, and fractionally distilled under nitrogen [Ellis & Reid J Am Chem Soc 54 1674 1932]. It has a foul odour. [Beilstein 1 IV 1390.]

Health Hazard

Inhalation of vapor causes muscular weakness, convulsions, respiratory paralysis. High concentrations may cause pulmonary irritation. Liquid irritates eyes and skin. Ingestion causes nausea and irritation of mouth and stomach.

Air & Water Reactions

Highly flammable. A very dangerous fire hazard. Very slightly soluble in water.
