2-Propanethiol Chemical Properties,Usage,Production

Chemical Properties

liquid with an exceedingly unpleasant smell

Occurrence

2-Propanethiol is a volatile sulfur compound that is reported to occur in irradiated beef.

Uses

2-Propanethiol is used in preparation of polyol block copolymer. It is also used as standard for petroleum analysis; as intermediate; as natural gas odorant.

Definition

ChEBI: 2-Propanethiol is an alkanethiol that is propane substituted by a sulfanyl group at position 2.

Preparation

2-Propanethiol is synthesised by the reaction of sodium hydrosulfide and brominated isopropane.

General Description

Isopropyl mercaptan is a white liquid with a strong skunk-like odor. (USCG, 1999)

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

2-Propanethiol is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. May liberate hydrogen sulfide when mixed with an acid.

Hazard

Highly flammable, dangerous fire hazard.

Health Hazard

Inhalation causes loss of sense of smell, muscular weakness, convulsions, respiratory paralysis. Ingestion causes nausea and vomiting. Contact with eyes or skin causes irritation.

Purification Methods

Purify it as for propane-1-thiol above. [Beilstein 1 IV 1498.]
