| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| application | dodecane is used as a solvent and distillation driver, and is also one of the average components of diesel. After the linear dodecane and concentrated sulfuric acid undergo a sulfonation reaction, the sodium can be transferred to make the surfactant sodium dodecyl sulfonate. |
| use | used as a standard substance for organic synthesis intermediates, solvents and chromatographic analysis. It is used to produce dodecanoic acid, linear alcohol and halogenated alkane, and is used as the main raw oil for daily chemical products. Gas chromatography analysis standard. Organic synthesis. |
| Production method | It is obtained by the reaction of bromohexane and sodium metal. |
