Castor oil properties: Castor oil contains large amounts of ricinoleic acid (over 80%), so with many unique properties:
1. easy to dissolve in ethanol, sparingly soluble in petroleum ether. The existence of this feature easier to distinguish the castor oil with other oils .
Castor oil properties 2. castor oil viscosity much higher than 25 when 680CPS, a viscosity index of 84, a low friction coefficient .
Meanwhile castor oil insoluble in gasoline, low freezing point, flash point higher . Castor oil mobility, refined castor oil is still flowing at -22, -50 quench no turbidity is ideal for aerospace and high-speed mechanical power belt lubricants and protective oil.

                      
Castor oil properties 3 .has a strong optical activity, because of its essential fatty acids - at 12 after ricinoleate asymmetric carbon atoms.

5.The relative density and acetyl values ​​are greater than the general castor oil.
Castor oil properties 6.hardly occurs castor oxidative rancidity in the air, good storage stability, is a typical non-drying liquid oil.
