1. Basic Info
Name: Soybean oil
Alias: Soy oil, Glycine soja oil
CAS No.: 8001-22-7
Composition: Mixed triglycerides of linoleic acid, oleic acid, palmitic acid, stearic acid, linolenic acid; complex mixture without single fixed molecular formula
Main representative triglyceride skeleton general formula: C57H100O6
Main fatty acid components: C16H32O2, C18H34O2, C18H32O2, C18H30O2
2. Physical & Chemical Properties
Physical Properties
- Appearance: Light yellow clear oily liquid, refined grade nearly colorless; crude oil dark yellow
- Odor: Mild characteristic soybean bean fragrance, deodorized oil almost odorless
- Solubility: Insoluble in water; miscible with ether, chloroform, hexane, ethanol; slightly soluble in methanol
- Density (20℃): 0.918–0.925 g/cm3
- Refractive index nD20: 1.472–1.476
- Flash point: 315 ℃
- Solidification point: -10 ~ -16 ℃
- Hygroscopy: Non-hygroscopic; absorbs oxygen in air to oxidize and rancidify
Chemical Properties
- Structure: Vegetable unsaturated triglyceride, rich in double bonds (linoleic acid, linolenic acid)
- Oxidation resistance: Unsaturated double bonds easy to auto-oxidize under light, high temperature, air, produce peroxide and rancid odor; need antioxidants (VE, TBHQ) for preservation
- Saponification reaction: Reacts with strong alkali to generate soap and glycerol
- Hydrogenation: Double bonds can be catalytically hydrogenated to produce hydrogenated soybean oil (hard fat)
- Transesterification: Reacts with short-chain alcohols to synthesize biodiesel fatty acid methyl ester
- Thermal stability: Stable below 180℃; long-time high temperature over 220℃ crack, polymerize, produce harmful polar substances
- Acid-base stability: Stable under neutral condition; strong acid/alkali catalyzes hydrolysis to free fatty acids and glycerol
3. Main Application Fields
1. Edible Food Raw Material (Core Application)
- Household cooking oil, frying oil, salad oil, blending oil base stock
- Raw material for margarine, shortening, cream, baked pastry, instant food
