N-HENEICOSANE Usage And Synthesis

Chemical Properties

white waxy solid

Uses

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.

Synthesis Reference(s)

Tetrahedron Letters, 17, p. 2643, 1976 DOI: 10.1016/S0040-4039(00)91757-X

General Description

Crystals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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.
