Castor oil press
Castor oil press
Castor oil press Castor oil is a triglyceride of a fatty acid. Castor oil is present in the seeds of castor, and its content is 35% to 57.% ". Castor oil is prepared by squeezing or solvent extraction. Castor oil fatty acid contains 90% ricinoleic acid (9-alkenyl-12 hydroxyoctadecanoic acid). The hydroxyl value is 163 mgKOH / g, the hydroxyl content is 4.94%, the molecular weight is 929.26 as the hydroxyl group, and the castor oil is calculated as the hydroxyl group With 70% trifunctionality and 30% difunctionality, the average hydroxyl functionality is 2.7. Polyurethane adhesive made with castor oil as raw material has good low temperature performance, hydrolysis resistance and excellent electrical insulation

Polyurethane adhesive made with castor oil as raw material has good low temperature performance, hydrolysis resistance and excellent electrical insulation

Castor oil properties
Castor oil contains a large amount of ricinic acid (more than 80%), so it has many unique properties:
1. Easily soluble in ethanol, difficult to dissolve in petroleum ether. The presence of this property makes it easier to distinguish castor oil from other oils.
2. Viscosity is much higher than general grease, at 680CPS at 25, viscosity index is 84, and friction coefficient is very low (0.1).
Castor oil has good fluidity, refined castor oil can still flow at -22, and no turbidity after quenching at -50. It is an ideal lubricant for aviation and high-speed machinery and a protective oil for power belts.
3It has strong optical rotation because its asymmetric carbon atom in ricinolic acid, its main fatty acid, is after the 12th position.
4The dielectric constant is about 4.30, which is the highest among common greases.
5. The relative density and acetyl value of castor oil are higher than those of ordinary oils.
6. Castor oil hardly undergoes oxidative rancidity in the air, has good storage stability, and is a typical non-drying liquid oil
