Potassium hydroxide is a common inorganic base with a chemical formula of KOH and a molecular weight of 56.1. It is a white powder or flake solid at room temperature.

Helium is a rare gas. Its English name is Helium, and its element symbol is He. It is a colorless and odorless inert gas. Its chemical properties are not vivid. Under normal conditions, it is difficult to react with other substances.

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.

Oxygen is a simple substance composed of oxygen. The chemical formula O2 has more vivid chemical properties, and most of the elements can react with oxygen.

Biphenyl is found in coal tar, crude oil and natural gas. The preparation methods of biphenyl include the chemical composition method of making biphenyl through benzene pyrolysis and the separate extraction method of making biphenyl through various coal tar fractions. The mass fraction of biphenyl in coal tar is 0.20%-0.40%, and coal tar extraction method and chemical composition method coexist.

Acetic acid, also called acetic acid, glacial acetic acid, chemical CH3COOH, is an organic monovic acid, which is the main component of vinegar.

Only a small part of ammonia molecules react with water to form ammonia monohydrate, which is a weak base that only exists in ammonia.

Antioxidant is a kind of chemical substance. When it is only a small amount in the polymer system, it can delay or inhibit the progress of the polymer oxidation process, thereby preventing the aging of the polymer and prolonging its service life. It is also called " Anti-aging agent".

A substance that can reduce the surface tension of water, solution, suspension, etc., prevent the formation of foam, or reduce or eliminate the original foam. [1]

When the temperature drops to 2.18K, the properties of liquid helium will change suddenly, the viscosity is very small, and it becomes a super fluid that can flow upwards along the wall of the container. The thermal conductivity is 800 times that of copper. It becomes a thermal conductor with excellent thermal conductivity. Its specific heat capacity, surface tension, and compressibility are all abnormal. This abnormal liquid is called liquid helium II, and the normal liquid helium is called liquid helium I.

The propanol, but also glycerol, chemical formula is C3H8O3, colorless, odorless, sweet, and appearance showing a clear liquid, is an organic substance, can absorb moisture from air, can also absorb hydrogen sulfide, hydrogen cyanide and sulfur dioxide .

The octane is the most important quality indicator of the vehicle gasoline.

Ammonia, also known as Amonia water, can be written as NH3(aq), which is an aqueous solution of ammonia, colorless, transparent and has a pungent odor.

The solubility in water was 549 g / L at 20 ° C. Relative density 2.400 (deposit density: 0.7).

Carbonide is a kind of inorganic compound with CS2 chemical formula. It is a colorless liquid and is a common solvent.
