1-Dodecanethiol Chemical Properties,Uses,Production

Chemical Properties

clear liquid

General Description

Oily colorless liquid with a mild skunk odor. Freezing point 19°F.

Air & Water Reactions

Air and moisture sensitive. Insoluble in water. Reacts vigorously with water or steam.

Reactivity Profile

1-Dodecanethiol is incompatible with bases, oxidizing agents, reducing agents and alkali metals. Easily oxidized to disulfide.

Health Hazard

Liquid is irritating to skin, eyes, and mucous membranes. Ingestion may cause nausea. Repeated skin exposure can cause dermatitis and may produce a sensitizing effect.

Fire Hazard

Special Hazards of Combustion Products: Poisonous and irritating gases (e.g., sulfur dioxide) are generated in fires.

Purification Methods

Dry it with CaO for several days, then distil it from CaO. [Beilstein 1 IV 1851.]
