| Hazard Information | Back Directory | [General Description]
Hexagonal leafs. | [Reactivity Profile]
Saturated aliphatic hydrocarbons, such as N-HEPTADECANE(629-78-7), may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water. | [Air & Water Reactions]
Flammable. Insoluble in water. | [Fire Hazard]
Flash point data for this compound is not available,but N-HEPTADECANE is probably combustible. | [Chemical Properties]
colourless liquid or white solid | [Application]
Heptadecane was used as an internal standard in the reaction to study the first direct comparison of kava lactone extraction efficiencies. It was also used as the appropriate suspended solvent for the extraction and concentration of EO (essential oil). | [Definition]
ChEBI: A straight-chain alkane with 17 carbon atoms. It is a component of essential oils from plants like Opuntia littoralis and Annona squamosa. | [Preparation]
Gas-phase dehydrogenation of n-alkanes over noble-metal catalysts yield the corresponding n-alkenes at low conversion rates (ca. 10%) with predominantly internal double bonds. The corresponding alkenes can be isolated in high purity by selective molecular-sieve processes. | [References]
