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.
