Gas introduction
Propane is an organic compound with the chemical formula CH3CH2CH3. It is a colorless and odorless gas. It is slightly soluble in water, soluble in ethanol and ether. It has stable chemical properties and is not easy to react chemically. It is often used as a refrigerant, internal combustion engine fuel or organic synthesis raw material.
Class 2.1 flammable gas. Flammable gas; it can form an explosive mixture when mixed with air, and it is dangerous to burn and explode when it encounters heat sources and open flames; it will react violently when it comes into contact with oxidants; the gas is heavier than air and can spread to a considerable distance at a lower level. It will catch fire and burn back when it encounters a fire source.
