Химические свойства

colourless crystals or wax-like solid

Использование

n-Eicosane is a saturated aliphatic hydrocarbon, which is used to form candles and paraffin waxes with solar energy storage capacity. It is also used in cosmetics, lubricants, plasticizers and in the petrochemical industry. Further, it is useful for special surfactants and in the preparation of certain organic chemicals. In addition to this, it is used as a chromatographic analysis reference material.

Общее описание

Colorless crystals or white crystalline solid.

Реакции воздуха и воды

Insoluble in water.

Профиль реактивности

Saturated aliphatic hydrocarbons, such as N-EICOSANE, 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.

Пожароопасность

N-EICOSANE is combustible.
