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. Therefore, in actual application, it is often based on the variety, use and processing method of engineering plastics, using the strengths of various additives and cooperating to produce synergistic effects.

Physical nature

Colorless concierge fluids have a fierce scent. Insoluble in water, dissolved in ethanol and ether.

Benzyl alcohol, paf alcohol, 2-chloroethanol, ethylene glycol, furfural, dimethylformamide and acetonitrile were dissolved at room temperature. No corrosive metal.

Appearance: watery bright liquid with pleasant ketone-like fragrance.Main uses: Used as a solvent for spray paint, nitrocellulose, some fiber ethers, camphor, grease, natural and synthetic rubber.Precautions for storage and transportation: Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The warehouse temperature should not exceed 30℃. Avoid direct sunlight. Keep the container sealed. It should be stored separately from oxidant. Lighting, ventilation and other equipment in the storage room should be explosion-proof. Technical measures for fire prevention and explosion protection should be taken when storing tanks. It is forbidden to use mechanical equipment and tools that are prone to sparks. Handle it lightly to avoid damage to packaging and containers. ERG Raiders: 127 ERG Raiders Classification: Flammable liquid

mercaptan wrapped in fuel is malodorous and corrosive, which reduces the lead content of gas. except, mercaptan is also an oxidation initiator, which can promote the oxidation and condensation of risky components in fuel to gel, resulting in terrible garage balance of gasoline. cobalt phthalocyanine sulfonate is an powerful catalyst for disposing of mercaptan sulfur from heavy oil, and it has the identical effect. whilst in use, dissolve the catalyst in 10% alkali solution, heat it slightly for a time frame, and stir to dissolve it before use. easy to function, dilute alkali liquor can be regenerated and recycled.

insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils, it's miles the skeleton factor of triglyceride molecules.

Glycerol, also called glycerol, with the chemical formula c3h8o3, is colorless, odorless, sweet, with a clean and viscous liquid appearance. it's miles an organic substance that may take in moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils, it's miles the skeleton factor of triglyceride molecules.

citric acid is without problems soluble in water and ethanol, its solubility is 59% at 20℃, and the ph of its 2% aqueous solution is 2.1.

its density is 1.542g/cm3, its melting point is 153-159℃, and water and carbon dioxide are differentiated and launched above a hundred seventy five℃. citric acid is without problems soluble in water and ethanol, its solubility is 59% at 20℃, and the ph of its 2% aqueous solution is 2.1.

the crystal form of citric acid is exclusive due to distinctive crystallization conditions. it's miles barely weathered in dry air and hygroscopic in humid air. when heated, citric acid may be differentiated into diverse merchandise, that could react with acid, alkali, glycerin, and so on.
