| 1-Heptanethiol Usage And Synthesis |
| Chemical Properties | clear liquid | | Chemical Properties | 1-Heptanethiol is a flammable, colorless
liquid with a strong odor. | | Chemical Properties | Colorless liquid, onion aroma. | | Aroma threshold values | High strength odor, sulfurous onion type; recommend smelling in a 0.10% solution or less. | | General Description | Colorless liquid with a strong unpleasant odor. Mp: -41.3°C; bp: 177°C. Density: 0.84 g cm-3. Insoluble in water. | | Reactivity Profile | 1-Heptanethiol is combustible (flash point at or above 100°F and below140°F). Incompatible with oxidizing agents, strong acids and strong bases, alkali metals, and nitric acid. Can react with water, steam or acids to produce toxic and flammable vapors. Reacts violently with powerful oxidizing agents such as calcium hypochlorite(Ca(OCl)2) to generate SOx. Reacts with hydrides to form flammable H2 gas; reacts with halogenated hydrocarbons to yield HX. Reacts exothermically with aldehydes. Emits toxic compounds of sulfur when when heated to decomposition. | | Potential Exposure | Used as a chemical intermediate for
fuels, dyes, pharmaceuticals; and to make other chemicals. | | Shipping | UN1228 Mercaptans, liquid, flammable, toxic,
n.o.s. or Mercaptan mixtures, liquid, flammable, toxic,
n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid,
6.1-Poisonous materials, Technical Name Required. | | Incompatibilities | Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides, alkali metals and reducing
agents. | | Waste Disposal | Dissolve or mix the material
with a combustible solvent and burn in a chemical incinera tor equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. |
