| | 1-Pentanethiol Usage And Synthesis |
| Chemical Properties | clear colorless liquid; meaty aroma. slightly soluble in water, easily soluble in alcohol and ether. | | Uses | 1-Pentanethiol is a raw material for organic synthesis. It is mainly used in the organic synthesis of sulfur compounds. | | Uses | 1-Pentanethiol can be used as additives for hair coloring agents. | | Preparation | 1-Pentanethiol is synthesized from n-pentyl alcohol and hydrogen sulfide catalyzed by thorium dioxide. | | Definition | ChEBI: 1-Pentanethiol is an alkanethiol. | | Aroma threshold values | High strength odor; recommend smelling in a 0.10% solution or less. | | General Description | 1-Pentanethiol appears as a clear colorless to light-yellow liquid with an offensive odor. Flash point 65°F. Less dense than water and insoluble in water. Hence floats on water. Vapors are heavier than air. May be toxic by inhalation. | | Air & Water Reactions | Highly flammable. Insoluble in water. | | Reactivity Profile | 1-Pentanethiol is incompatible with oxidizing agents, reducing agents, alkali metals, calcium hypochlorite, concentrated nitric acid . | | Health Hazard | Inhalation may cause nausea because of offensive odor. Contact with eyes or skin causes slight irritation. Ingestion may cause vomiting. | | Safety Profile | Moderately toxic by inhalation. A weak sensitizer and allergen. Local contact may cause contact dermatitis. A flammable liquid and dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidming materials. Hypergolic reaction with concentrated nitric acid. To fight fire, use foam, CO2, dry chemical. See also MERCAPTANS | | Solubility in organics | Soluble in alcohol, perfume and flavor materials.
| | Purification Methods | Dissolve the thiol in aqueous 20% NaOH, then extract with a small amount of diethyl ether. The aqueous solution is acidified slightly with 15% H2SO4, and the thiol is distilled out, dried with CaSO4 or CaCl2, and fractionally distilled under nitrogen.
