1. Basic Information
Name: Capric acid
Alias: Decanoic acid, n-Decanoic acid
CAS No.: 334-48-5
Molecular Formula: C10H20O2
Molecular Weight: 172.26
2. Physical & Chemical Properties
Physical Properties
- Appearance: White crystalline solid at room temperature; melts into colorless transparent oily liquid above melting point
- Odor: Mild characteristic fatty acid odor, slightly rancid smell at high concentration
- Solubility: Insoluble in cold water, slightly soluble in hot water; freely soluble in ethanol, methanol, acetone, chloroform, ether, vegetable oils
- Melting Point: 30–32 ℃
- Boiling Point: 270 ℃
- Density (40 ℃, liquid): 0.886 g/cm3
- Refractive Index nD40: 1.4285
- Volatility: Low volatility at normal temperature; volatile with water vapor under heating
- Hygroscopy: Non-hygroscopic
Chemical Properties
- Structure: Straight-chain saturated fatty acid with 10 carbon atoms, single terminal carboxyl group
- Neutralization reaction: Reacts with alkali (NaOH, KOH, ammonia) to generate decanoate soap salts with good surface activity
- Esterification: Condenses with monohydric alcohols, polyols to form capric acid esters (flavors, plasticizers, emulsifiers)
- Amidation: Reacts with amines to produce fatty acid amides, used as slip agents and surfactants
- Hydrogenation: Saturated carbon chain, no addition reaction with hydrogen under normal conditions
- Thermal stability: Stable below 200 ℃; high temperature above 280 ℃ undergoes decarboxylation and cracking
- Oxidation resistance: Saturated structure, far less susceptible to oxidative rancidity than unsaturated fatty acids
- Compatibility: Compatible with most organic solvents, oils; reacts with strong bases, oxidizing agents under heating
3. Main Application Fields
1. Synthetic Ester Intermediate (Core Application)
- Raw material for methyl caprate, ethyl caprate, glyceryl tricaprate; used as food flavor, cosmetic emollient, lubricant base oil
