氯代十八烷 (CAS No.3386-33-2)
- 物化性质
- 常温下为白色至微黄色蜡状固体。熔点22~26℃，沸点348℃（常压），195~200℃/0.67kPa（减压）。密度0.868 g/cm³（25℃），折射率nD20=1.4520~1.4540。不溶于水，易溶于乙醇、乙醚、丙酮、苯、石油醚等多数有机溶剂。常温密封条件下稳定，应避免与强氧化剂、强碱接触；氯原子可发生亲核取代、消除反应，高温条件下可能发生热分解。

Product Name:1-Chlorooctadecane
English Name:1-Chlorooctadecane
CAS No.:3386-33-2
Aliases:Stearyl chloride, n-Octadecyl chloride, Octadecyl chloride
Molecular Formula:C18H37Cl
Physical Properties:White to slightly yellow waxy solid at room temperature. Melting point 22–26°C; boiling point 348°C (normal pressure), 195–200°C/0.67 kPa (reduced pressure). Density 0.868 g/cm³ at 25°C; refractive index nD20 = 1.4520–1.4540. Insoluble in water; readily soluble in most organic solvents such as ethanol, diethyl ether, acetone, benzene and petroleum ether. Stable under sealed storage at room temperature; avoid contact with strong oxidizers and strong bases. The chlorine atom can undergo nucleophilic substitution and elimination reactions, and thermal decomposition may occur at high temperature.
Uses:Used as a long-chain alkylating agent to introduce an octadecyl chain into target molecules via nucleophilic substitution of the chlorine atom, serving as an important raw material for synthesizing long-chain aliphatic compounds, surfactants and lubricant additives. Also used to prepare long-chain aliphatic derivatives such as octadecanol and octadecylamine. In scientific research, it is commonly employed as a model compound of long-chain haloalkanes to study the effects of carbon chain length on physicochemical properties and reactivity, and as a reference standard for development and optimization of chromatographic analytical methods.
