1. Basic Info
Name: Palm oil
Alias: Elaeis Guineensis Fruit Oil, Refined Palm Oil
CAS No.: 8002-75-3
EINECS: 232-316-1
Molecular Formula: Complex mixed triglyceride mixture (No single fixed molecular formula)
Molecular Weight: N/A (Mixed component, no uniform molecular weight)
2. Physical & Chemical Properties
Physical Properties
- Appearance: Crude red palm oil is orange-red semi-solid; refined palm oil is pale yellow, solid below 25℃, transparent liquid after heating above 30℃
- Odor: Refined grade is odorless; crude oil has mild natural plant fatty aroma
- Solubility: Insoluble in water; miscible with ethanol, ether, chloroform, mineral oil, other vegetable oils
- Density (50℃): 0.921–0.925 g/cm3
- Melting Point: 30–40 ℃
- Refractive Index (40℃): 1.453–1.459
- Flash Point: ≥230 ℃, high smoke point, suitable for high-temperature frying
- Iodine Value: 48–57 g I?/100g
- Saponification Value: 195–205 mg KOH/g
- Hygroscopy: Non-hygroscopic; absorbs slight air oxygen for long-term open storage
- Main fatty acid composition: Palmitic acid C16H32O2 (37–45%), Oleic acid C18H34O2 (38–45%), Linoleic acid C18H32O2 (9–12%), Stearic acid C18H36O2 (3–5%)
Chemical Properties
- Main composition: Mixed glycerol triester of saturated & unsaturated fatty acids, balanced saturated & unsaturated fat ratio
- Oxidation stability: Higher saturated fatty acid content, strong anti-oxidation, not easy to produce harmful oxides during high-temperature cooking
- Saponification reaction: Reacts with sodium/potassium hydroxide under heating to produce soap and glycerin
- Hydrogenation performance: Can be hydrogenated to produce hardened palm oil with higher melting point for margarine & shortening
- Fractionation property: Separable into liquid palm olein and solid palm stearin via low-temperature fractionation for different industrial uses
- Thermal stability: Stable below 220℃; over 250℃ thermal cracking occurs, producing volatile aldehydes and ketones
- Acid-base compatibility: Stable in neutral environment; hydrolyzed under strong acid/alkali heating to free fatty acids and glycerol
- Compatibility: Compatible with all lipophilic raw materials; incompatible with strong oxidants, concentrated strong acid
3. Main Application Fields
1. Food Industry (Core Application)
- High-temperature frying oil: High smoke point, stable texture, widely used for fried chicken, potato chips, instant noodles, fried dough sticks
- Baking raw material: Make biscuits, cakes, pastries, margarine, shortening; endows products crisp texture and stable shape
- Edible blending oil: Mix with soybean oil, rapeseed oil to balance fatty acid ratio, reduce production cost
- Confectionery & cream: Raw material for chocolate cream, filling cream, ice cream base oil, improves product smoothness
- Infant food & instant food: Add to instant powder, cereal products as energy lipid source
2. Daily Chemical & Cosmetic Industry
- Soap raw material: Large dosage for laundry soap, bath soap, mild foam, low cost
- Personal care base oil: Emollient raw material for body lotion, cream, hand cream, soap base; moisturizes skin
- Surfactant intermediate: Hydrolyze to fatty acids for producing fatty alcohol, fatty acid ester emulsifiers
3. Industrial Chemical Field
- Biodiesel raw material: Transesterified with methanol to prepare clean biodiesel fuel
- Metal processing auxiliary: Hot tin plating flux, metal rust-proof lubricant
- Lubricant & release agent: Mold release agent for plastic, rubber, aluminum alloy casting
- Fatty acid & fatty alcohol production: Hydrolysis raw material for industrial stearic acid, oleic acid, glycerin extraction
4. Feed Industry
Feed-grade palm oil additive for livestock, poultry, aquaculture; improves feed energy value, accelerates animal weight gain
