н-гексакозана

Химические свойства

white crystalline solid

Использование

Hexacosane can be used:

• To prepare sulfonated hexacosanes, which are used as phase-change materials in the latent heat thermal energy storage process.
• As a model n-alkane to study the solid-liquid equilibrium of binary mixtures in N,N-dimethylacetamide and N,N-dimethylformamide.

Определение

ChEBI: A straight-chain alkane comprising of 26 carbon atoms.

Общее описание

Colorless crystals. Occurs in many natural products.

Реакции воздуха и воды

Insoluble in water.

Профиль реактивности

Saturated aliphatic hydrocarbons, such as N-HEXACOSANE, 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

Flash point data on N-HEXACOSANE is not available, but N-HEXACOSANE is probably combustible.

Методы очистки

Distil hexacosane under vacuum and recrystallise it from diethyl ether. [Beilstein 1 IV 583.]
