Castor oil is a kind of fatty acid triglyceride, which exists in castor bean seeds, and the content is between 35% and 57.%.
do you know? These unique properties of sesame oil?
1. It is easy to dissolve in ethanol, and easy to dissolve in petroleum ether. Castor oil is a light yellow viscous non-drying oil. Except for fatty acid hydrocarbons, most organic solvents can dissolve it, especially. This feature makes it easy to distinguish castor oil from other fats.
2. Castor oil has good color retention, color retention, softness, dispersion, wetting, lubrication, low temperature, electrical and biological properties.
3. Castor oil can undergo a variety of chemical reactions through OH groups, double bonds and ester bonds,
4. The viscosity is much higher than that of ordinary grease, 680CPS at 25°C, viscosity index of 84, and very low friction coefficient (0.1).
5. Castor oil has good fluidity. The refined seaweed oil can still flow at -22, and is not turbid at -50. It is an ideal lubricant for aviation and high-speed machinery and a protective oil for power belts.
6. Since the number of asymmetric carbon atoms is after the 12th position, it has strong optical rotation.
7. The dielectric constant is about 4.30, which is the highest content in common grease.
8. The relative density and acetyl value of castor oil are higher than ordinary oils.
9. Castor oil is a typical non-drying liquid oil. It has almost no oxidative rancidity in the air and has good storage stability.
