castor oil

Descripción del producto

Chinese name: castor oil English name: Castor oil EINECS: - Formula: C*7H**4O9 Properties: This product is non-drying oil, almost colorless or light yellow transparent viscous flammable liquid with special smell. CAS: ********4 EINECS No. :**2 *****8 Molecular formula: C*7H**4O9 MW: **3.*4 Melting point: **0 ℃ Weight: **2 English name: Castor Oil Nature Description: Near colorless or slightly yellow, transparent viscous flammable liquids. Freezing point **0 ℃, relative density (*5/*5 ℃) 0.****0.**5, refractive index nD**1.****1.**0. Ignition (℃) **2 Iodine value (g iodine / **0g oil) ****6 Saponification value (mgKOH / g oil) ******7 Thiocyanate values ****2 The total fatty acid content (%) *6 Average molecular weight fatty acids ******0 Castor oil fatty acid composition (%): Stearic acid 0.**3.0 Dihydroxy stearic acid 0.**2.0 Oleic acid **9 Linoleic acid 2.**3.5 Ricinoleic acid ****8 Physical and chemical properties: 1. Easily dissolved in ethanol, hardly dissolved in petroleum ether. The existence of this feature easier to distinguish the castor oil and other oils. 2. Viscosity oil is much higher than the average, *5 when **0CPS, viscosity index of *4, the friction coefficient is low (0.1), while castor oil is not soluble in gasoline, low freezing point, high ignition. Good mobility of castor oil, refined castor oil can flow when in the **2, **0 no turbidity after quenching, is ideal for aerospace and high-speed machinery and power belt lubricant to protect the oil. 3. Has a strong optical activity, since its main fatty acids - castor alkyd asymmetric carbon atom in the **-bit later. 4. Dielectric constant is about 4.*0, the highest of oil is common. 5. Acetylated castor oil relative density and the values are higher than normal oil. 6. Castor oil in the air almost no oxidative rancidity, storage stability, is a typical liquid-drying oil.
