Industrial production method of polymethane: Generally, in the titanium alloy reactor or polymethane reactor, the card (ka) is used as a catalyst, and the reaction can be used to obtain the initial state of polymethane at 800 degrees Celsius and 800 atmospheres.
Since methane is saturated, it is not possible to produce polymethane by conventional polymerization methods. However, in 2006, Dr. Chaoli Antimony published the theory of curved keys of carbon.
Mr. Liu Peng (Zhao Mingyi), a famous Chinese physicist and chemist, put 38% hydrochloric acid under a high pressure of 250 and 500 MPa, and used antimony elements and card elements as catalysts to finally generate superhydrochloric acid.

Methane, chemical formula CH4, is the simplest hydrocarbon that consists of one carbon and four hydrogen atoms hybridized by sp3, so the structure of the methane molecule is a regular tetrahedral structure, and the bond lengths of the four bonds are the same and the bond angles are equal. In its standard state, methane is a colorless and odorless gas.
The biogas produced when some organic matter decomposes in the absence of oxygen is actually methane. Theoretically, the bonding formula of methane can be expressed as a point "·" But I haven't actually seen this usage, probably because of "·" The number can also represent electrons. That's why methane is considered unbonded in secondary school.
Methane is mainly used as a fuel, such as natural gas and coal gas, and is widely used in civil and industrial applications. As a chemical raw material, it can be used to produce acetylene, hydrogen, synthetic ammonia, carbon black, carbon disulfide, methylene chloride, methylene chloride, chloroform, carbon tetrachloride and hydrocyanic acid.
Chemical reaction. The main chemical reactions of methane are: combustion, reintegration of steam into gas, and halogenation.
In general, the methane reaction is difficult to control. Methane can be oxidized to methanol, but it is generally very difficult to complete this chemical reaction, because in general, the oxidation reaction products of methane are usually carbon dioxide and water, and it is difficult to produce methanol even if oxygen is insufficient.
However, this oxidation reaction can be easily done with the help of enzymes, such as methane monooxygenase, but the yield cannot reach the scale of industrial production.

Methane is an organic compound.
Methane is the simplest organic matter and the least carbonaceous hydrocarbon. Methane is widely distributed in nature and is the main component of natural gas, biogas, pit gas, etc., commonly known as gas. It can be used as a fuel and in the production of hydrogen, carbon black, carbon monoxide.
Raw materials for acetylene, hydrocyanic acid and formaldehyde.
On April 2, 2018, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory made the first direct proof that methane causes the greenhouse effect on the Earth's surface.

Methane Applications:
Methane pyrolysis can obtain carbon black, which is used as an additive for pigments, inks, paints and rubber; Chloroform.
and CCL4 are both important solvents. Methane is widely distributed in nature and is one of the main components of natural gas, biogas, and pit gas.
It can be used as fuel and raw material for the production of hydrogen, carbon monoxide, carbon black, acetylene, hydrocyanic acid and formaldehyde. Methane is used as a standard fuel for calorific value testing in water heaters and gas furnaces. Production of standard gas and correction gas for combustible gas alarms.
It can also be used as a carbon source for vapor chemical deposition of solar cells and amorphous silicon films. and methane as a raw material for the production of pharmaceutical and chemical synthesis.
In addition to being used as fuel, it is widely used in the synthesis of ammonia and urea.

Methane, with the molecular formula CH4, is a colorless and odorless flammable gas with a boiling point of -164 and a melting point. Slightly soluble in water, soluble in ethanol, ether and other organic solvents, mixed with air can form a first-class mixture.
Methane can be used as a fuel; Industrially, it is mainly used for the production of syngas, for the manufacture of synthetic ammonia, hydrogen and methanol, etc., and can also be used for the production of acetylene, ethylene, carbon disulfide, hydrocyanic acid and carbon black; Methane chlorination is available.
Mono, di, chloroform and carbon tetrachloride.
Methane content distribution
Methane and hydrogen are also present in Uranus' atmosphere. According to experiments by scientists at the German Institute for Nuclear Physics, methane is produced in both plants and leaf litter, and the amount of methane produced increases with temperature and sunlight. In addition, plants produce 10 to 100 times more methane than decaying plants.
They estimate that plants produce 10 to 30 percent of the world's methane each year.
Methane found in planets According to foreign reports, American astronomers announced on the 19th that they found methane in the atmosphere of a planet outside the solar system for the first time, which is the first time that scientists have detected organic molecules on an extrasolar planet, thus increasing the hope of confirming the existence of life outside the solar system. The team also confirmed previous speculation that the planet, called HD 189733b, had water in its atmosphere.

1. Methane is widely distributed in nature and is one of the main components of natural gas, biogas, pit gas and coal gas. It can be used as fuel and raw material for the production of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde.
2. Methane is a very important fuel and the main component of natural gas, accounting for about 87%. At room temperature under standard pressure, methane is colorless and odorless; The special smell of household amur is an artificial scent that has been added for safety, usually using methyl mercaptan or ethyl mercaptan.
3. In an atmospheric pressure environment, the boiling point of methane is 161 degrees. As long as the gas content in the air exceeds 5% or 15%, it is very flammable. Liquefied methane does not burn except in a high-pressure environment (usually 4-5 atmospheres).
The Chinese national standard stipulates that methane cylinders are brown with white characters.

Question 1: What is CH4 methane.
The simplest organic compounds. Methane is a colorless, odorless gas, boiling point, lighter than air, and it is a flammable gas that is extremely difficult to dissolve in water. Methane and air are a mixture in the right proportion, which can occur in case of sparks**.
The chemical properties are quite stable, and it generally does not react with strong acids, strong alkalis or strong oxidants (such as KMNO4). Under the right conditions, oxidation, pyrolysis and halogenation reactions will occur.
Methane is widely distributed in nature and is one of the main components of natural gas, biogas, pit gas and coal gas. It can be used as a fuel and raw material for the production of hydrogen, carbon monoxide, carbon black, acetylene, hydrocyanic acid and formaldehyde.
