Beschreibung
Heneicosane (also known as n-Heneicosane) is a potential organic phase-change material (PCM) used for thermal energy storage
[1]. In its pure form, it has a melting point of 313.55 K (approximately 40.4 °C) and offers advantages such as good stability, low supercooling and low cost. However, due to its relatively low thermal conductivity, it is often combined with highly thermally conductive fillers (such as graphene) to form composite materials, which are used in solar thermal energy storage, passive cooling of electronic devices, and waste heat recovery systems.
Chemische Eigenschaften
white waxy solid
Verwenden
Heneicosane is a long chain saturated aliphatic hydrocarbon found in coal tars and fossil organic matter. Heneicosane has a high flashpoint which makes it an inefficient fuel for use in the petrochemical industry. Heneicosane is usually present in the form of paraffin wax.
Definition
ChEBI: An alkane that has 21 carbons and a straight-chain structure. It has been isolated from plants like Periploca laevigata and Carthamus tinctorius.
Allgemeine Beschreibung
Crystals.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
Saturated aliphatic hydrocarbons, such as N-HENEICOSANE, 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.
