Product description:

Methane gas CH4 is the simplest organic matter. The methane molecule is a tetrahedral structure with four equal bond lengths and angles. Methane under standard conditions is a colorless and odorless gas. It is slightly soluble in water and soluble in organic solvents such as ethanol and ether.

Methane gas CH4 is an important fuel and chemical raw material. Natural gas with methane as the main component has a long history as a high-quality gas fuel with a calorific value of 882.0kJ/mol. Natural gas has been mined on a large scale and has become the world's third largest energy source. The calorific value of liquefied natural gas is 15% higher than that of jet kerosene. It is used in automobiles, marine speedboats, and supersonic aircraft. It can not only fly at high speed, but also save fuel. In addition to being used as fuel, it is widely used in the synthesis of ammonia, urea, and carbon black, and can also be used to produce methanol, hydrogen, acetylene, ethylene, formaldehyde, carbon disulfide, nitromethane, hydrocyanic acid, and 1,4-butanediol. Methane can be chlorinated to obtain dichloromethane, trichloromethane, and carbon tetrachloride.
