1. Basic Identification Information
| Parameter | English Specification/Value |
|---|---|
| IUPAC Name | Dodecane (systematic name: n-dodecane) |
| Common Name(s) | n-Dodecane; Dodecane; n-C₁₂; Laurane; Alkane C12 |
| CAS Registry Number | 112-40-3 |
| EC/EINECS Number | 203-967-9 |
| Molecular Formula | C₁₂H₂₆ |
| Molecular Weight | 170.34 g/mol |
| Chemical Class | Straight-chain aliphatic alkane; hydrocarbon solvent; fuel component; emollient base stock |
| Related Compound | n-Undecane (CAS 1120-21-4) (C11 alkane, lower boiling point); n-Tridecane (CAS 629-50-5) (C13 alkane, higher viscosity); Iso-dodecane (CAS 31807-55-3) (branched isomer, better skin spreadability for cosmetics) |
2. Physicochemical Properties
| Property Category | Specific Parameter | Specification/Value |
|---|---|---|
| Structural Features | Functional Groups | Saturated C-C single bonds; no polar functional groups (non-polar, hydrophobic structure with linear alkyl chain) |
| Physical Appearance | State & Color | Colorless, clear, mobile liquid; odorless (high-purity grade) or faint hydrocarbon odor (technical grade); waxy solid at low temperatures |
| Melting Point | -9.6 °C (lit.) (solidifies below this temperature into waxy crystals) | |
| Boiling Point | 216.3 °C (lit.); forms azeotropes with polar solvents (e.g., ethanol, boiling point 117 °C at 5% n-dodecane) | |
| Density (25 °C) | 0.748 g/cm³ |
