| Hazard Information | Back Directory | [General Description]
Colorless crystals or white crystalline solid. | [Reactivity Profile]
Saturated aliphatic hydrocarbons, such as N-EICOSANE(112-95-8), 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]

colourless crystals or wax-like solid | [Uses]
Eicosane is a long chain saturated aliphatic hydrocarbon. Eicosane has a high flashpoint which makes it an inefficient fuel for use in the petrochemical industry. Eicosane is used to form candles and paraffin waxes with solar energy storage capacity. | [Application]
n-Eicosane (chemical formula C₂₀H₄₂) is a long-chain alkane characterised by its non-toxicity, lack of chemical corrosiveness and excellent stability. With a melting point of approximately 38°C, which is very close to human body temperature (36.6°C), it is an ideal filling material for the textile industry. Used as a filler in phase-change materials (PCMs), it primarily serves as the core material for microcapsules, utilising the latent heat absorbed or released during the solid-liquid phase transition to regulate temperature. These microcapsules are widely used in the textile, construction and pharmaceutical sectors[2]. | [Definition]
ChEBI: Icosane is a straight chain alkane composed of 20 carbon atoms. It has been isolated from the leaves of Agave attenuata. It has a role as a plant metabolite. | [Purification Methods]

| Questions And Answer | Back Directory | [Biodegradation]
Studies have shown that N-EICOSANE can be degraded by the fungus Trichoderma sp. S019 in both liquid culture and soil, with a degradation rate of up to 77% in liquid culture. The degradation products are likely to be nonanoic acid, n-octadecane, hexadecanoic acid, oleic acid and stearic acid[1]. |
