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 an.
