What is tert-dodecylthiol?
The Uses of tert-dodecylthiol
Tert-dodecylthiol is used in the polymer industry and as a processing regulator, processing aid (i.e. pH value regulator, flocculant and precipitant), lubricant, for the manufacture of plastic materials, resins, paints, coatings, rubber products, and mining, among other things.
General Description
Clear white to pale yellow liquid with a repulsive odor.
Air & Water Reactions
Sensitive to moisture. Sensitive to prolonged exposure to air. Insoluble in water.
Reactivity Profile
tert-dodecylthiol is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Generate heat and in many cases hydrogen gas and possibly hydrogen sulfide with these materials. May liberate hydrogen sulfide upon decomposition or reaction with an acid. Incompatible with oxygen. Incompatible with strong oxidizing agents . May be sensitive to heat.
Fire Hazard
tert-dodecylthiol is combustible.
Safety Profile
Poison by ingestion. Moderately toxic by intraperitoneal route. A skin and eye irritant. Combustible when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use foam, Con, dry chemical. When heated to decomposition it emitstoxic fumes of SOx,. See also MERCAPTANS and SULFATE
