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.

Aspirational antioxidants should have the following conditions:
①Should have high anti-oxidation ability;
②Good compatibility with resin, no precipitation;
③Good processing function, non-volatile and non-decomposing at the processing temperature of high polymer;
④Good resistance to extraction, insoluble in water and oil;
⑤The color of itself is best to be colorless or light-colored, so as not to pollute the product;
⑥Non-toxic or low-toxic;
⑦Low price.
In fact, any kind of antioxidant can not fully meet these conditions.

Miscible with ether, diethylene glycol, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene and olive oil. It can react with hydroxyl-containing compounds, water, amines and compounds with active hydrogen atoms to generate carbamate, urea, semicarbazide, etc. Toluene is nitrated with mixed acid to obtain 2,4- and 2,6-dinitrotoluene, and then hydrogenated and reduced in the presence of nickel catalyst to obtain 2,4- and 2,6-diaminotoluene, which is then reacted with light in chlorobenzene solution. produced by gas reaction.

Glacial acetic acid is actually anhydrous acetic acid, an organic compound. As an organic acid, acetic acid will condense into ice-like crystals when it is lower than the melting point.
Acetic acid (AcOH) is corrosive and has a stimulating effect on eyes, respiratory tract, esophagus and stomach. It can cause vomiting, diarrhea, paralysis of the circulatory system, and even acidosis, uremia and hematuria, eventually leading to death.
The principle of potassium hydroxide removal of oil stains is actually a simple chemical principle. Since oil stains are a lipid chemical substance, from the analysis of its chemical composition, they are higher fatty acids and glycerides.
Ammonia water, also known as Ammonia water, is a solution of ammonia dissolved in water, is colorless and transparent liquid, has a special irritating odor, volatile, corrosive, weak alkaline, unstable and flammability and other characteristics.
Meta-xylene is an organic compound with a molecular formula of C8H10 and a molecular weight of 106. It is a colorless and transparent liquid with an odor similar to toluene. It is insoluble in water, but miscible in most organic solvents such as ethanol, ether and chloroform. Used as solvent, medicine, dye intermediate, perfume, etc.
Glycerol (also known as glycerol) is an organic substance that is colorless, odorless, sweet in taste, and has a clear, viscous appearance. It is miscible with any proportion of water, alcohol, amine and phenol, and the aqueous solution is neutral. Glycerin is a polyhydric alcohol humectant, and the hydroxyl groups form hydrogen bonds with water molecules in the molecular structure, which plays a good role in absorbing water and locking water. Glycerin has a wide range of uses, with more than 1,700 uses currently in use in food and industry.
Antioxidant is a kind of plastic additives that can effectively reduce the self-oxidation reaction speed of plastic materials and delay its aging degradation. It has a wide range of applications and is widely used in various polymer material products.
Good safety factor. Piping reflects that it can prevent the occurrence of explosion caused by partial over-temperature, and it is the safest and most reliable process route for ethylene oxide.
Titanium dioxide itself has strong photochemical activity, and is prone to inactivation, yellowing, powdering, etc. under the sun, especially ultraviolet rays. A layer of inorganic material is wrapped on the surface of the titanium dioxide, which not only gets rid of the above defects, but also improves the characteristics of the titanium dioxide product.
Hydroxypropyl toluene cellulose is a commonly used building material additive, which is widely used in industry and has a wide variety of types.
