1. Basic Product Profile
- Full IUPAC Name: dodecanoic acid
- Aliases: Dodecylic acid, C12 fatty acid
- CAS Number: 143-07-7
- EINECS: 205-582-1
- Molecular Formula: C12H24O2
- Molecular Weight: 200.32
- Chemical Classification: Saturated medium-chain fatty acid, surfactant raw material, cosmetic & food additive, pharmaceutical excipient
- Core Advantages
Straight-chain saturated C12 fatty acid mainly extracted from coconut oil and palm kernel oil. Excellent surface activity, mild irritation to skin and mucosa, easy biodegradation. Widely used to synthesize lauryl alcohol, sodium laurate, lauramide, nonionic/anionic surfactants; also applied in food emulsifiers, personal care products, pharmaceutical coating and lubricant additives.
2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: White flaky or granular crystalline solid
- Odor: Faint characteristic fatty odor
- Solubility: Insoluble in water; soluble in ethanol, methanol, chloroform, ether, acetone, hot vegetable oil
- Melting Point: 43–45 °C
- Boiling Point: 225 °C (100 mmHg)
- Density (50 °C liquid): 0.867 g/cm3
- Refractive Index nD50: 1.430–1.432
- Hygroscopy: Non-hygroscopic under normal dry storage
2.2 Chemical Properties
- Saturated long-chain carboxylic acid structure: Single terminal carboxyl group, no carbon-carbon double bonds
- Esterification reaction: Reacts with methanol, ethanol, glycerol, polyglycerol to produce fatty acid esters (emulsifiers, lubricants)
- Saponification: Neutralizes with sodium/potassium hydroxide to form laurate soap surfactants
- Amidation: Condenses with amines to generate lauramide diethanolamine (foaming agent, thickener)
- Acid & Alkali Stability: Stable in neutral and weak acid environment; reacts rapidly with strong alkali to form soap salts
- Thermal Stability: Resists oxidation at medium temperature; long-term heating above 150 °C causes slight yellowing and oxidation
- Photostability: Slightly yellow after long-term strong light exposure
- Compatibility: Compatible with most oils, nonionic surfactants; incompatible with alkaline mineral fillers, strong oxidants
3. Main Application Fields
