This feature makes castor oil can be easily distinguished from other oils. The viscosity of castor oil is much higher than the average grease, at a temperature of 25 is 680CPS Antonio Brown Kids Jersey , viscosity index is 84, low coefficients of friction (0.1). Meanwhile, castor oil is insoluble in gasoline, low freezing point, high-lighted. Castor oil with strong mobility, refined castor oil at -22 was still flowing, quenched at -50 without turbidity Antonio Brown Youth Jersey , is the ideal lubricants for aerospace and high-speed machine and the protective oil for power belt. Has a strong rotation, dielectric constant is about 4.30, the highest in common oils. The relative density and acetylated values of castor is greater than the general grease. Castor oil hardly occurs oxidative rancidity in the air, it has good storage stability, is a typical non-drying liquid oil.
聽
Castor oil is an almost colorless or slightly yellow clear viscous liquid, have a little smell, the taste is first light and then a little bitter. It is easy to dissolve in ethanol Antonio Brown Womens Jersey , can be arbitrarily mixed with ethanol, chloroform, diethyl ether or acetic acid. The relative density is 0.956 ~ 0.969 at 25. Refractive index is 1.478 ~ 1.480.
聽
Castor oil is extracted from castor beans, with high economic value, it is a medicinal laxatives; textile, chemical engineering and light industry sectors take castor oil as dyeing auxiliary, lubricants Authentic Antonio Brown Jersey , plasticizers, emulsifiers and manufacturing paint, soap and printing ink raw materials.

With different hydrogenation conditions processed castor oil can be obtained different kinds of products, therefore castor oil widely used in various industrial sectors. Castor oil is closest pure compound monoacid triglycerides. The unsaponifiable content in castor oil is less than 1%. Vitamin content is also lower (about 0.05).
聽
The oil content of castor beans is high, due to the different purposes of oil, the extracted oil methods also different, medicinal castor oil is cold pressed with a hydraulic press, the temperature does not exceed 50, otherwise some impurities will be dissolved in the oil and cannot for medicinal purposes. Castor oil obtained by cold pressed was known as the 1st. After its residue crushing, then pressing or leaching again to prepare the 3rd castor oil (No 2th) for industrial use. With screw press directly pressing#7# or castor oil obtained by pre-press-leaching only can be used as industrial oil.
