Ricia oil contains a lot of ricic acid (more than 80%), so many unique properties:

1. It is easy to dissolve in ethanol, which is difficult to dissolve in petroleum ether. This feature is more likely to distinguish between castor oil from other grease.

2. The viscosity is much higher than that of the general oil, and 25 is 680 cps, the viscosity index 84, the friction coefficient is very low (0.1).

The fluidity of castor oil is good, and the refined castor oil can still flow in -22.

3. There is a strong optically optically, because its main fatty acid - asymmetric carbon atom in ricin alcohol is 12.

4. The dielectric constant is about 4.30, which is the highest in common oil.

5. The relative density and acetyl value of castor oil are greater than the general oil.

6. Castor oil has almost no oxidative fat in the air, and the stability of storage is a typical inherent liquid oil.
