The total fatty acid content (%) 96

Average molecular weight fatty acids 290-300

Castor oil fatty acid composition (%):

Stearic acid 0.5-3.0

Dihydroxy stearic acid 0.6-2.0

Oleic acid 3-9

Linoleic acid 2.0-3.5

Ricinoleic acid 80-88

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, 25 when 680CPS, viscosity index of 84, 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 -22, -50 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 12-bit later. 4. Dielectric constant is about 4.30, 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.

Castor oil physical and chemical constants:

Use: for the production of sebacic acid, cold plasticizers, lubricants, spices, textile industry penetrant, emulsifier and so on. Castor oil is not edible. The textile, chemical and light industry sectors such as production assistant agent, lubricant, plasticizer punishment, torture and manufacture of emulsion paint, paint, soap and printing ink raw materials. For Turkey, marked oil, soap, plastics, lubricants and other manufacturers

Castor Oil obtained by the concentrated sulfuric acid to make a good surface active sulfate (commonly known as Turkey marked). Dehydrated castor oil with conjugated double bonds may be the dry oil. Conditional processing in different hydrogenated castor oil can be a variety of products, so castor oil is widely used in various industrial sectors.

Properties: colorless or light yellow transparent viscous liquid, is vomiting, has a special smell, the main component of castor oil acid (cis-12 - hydroxy-octadecadienoic en -9- acid; CH3 (CH2) 5CH (OH) CH2CH = CH (CH2) 7COOH) glycerol.
