Ethane is a simple alkane with the formula C2H6, which has many important properties and uses. In the field of chemical production raw materials, ethane is mainly used as fuel and chemical raw materials. The properties and uses of ethane will be described in detail in this paper.

1. Ethane Properties

1. Physical Properties
Ethane is a colorless, odorless, flammable gas with a density smaller than air and is difficult to dissolve in water. Under standard conditions, ethane has a boiling point of -88.6°C and a melting point of -183.3°C. The critical temperature of ethane is 32.2°C and the critical pressure is 4.87MPa.

2. Chemical properties The chemical properties of
ethane are relatively stable, but under certain conditions, substitution reactions, oxidation reactions, and cracking reactions can occur. Ethane and chlorine in the light conditions can occur under the substitution reaction, the generation of chloroethane, dichloroethane and other chlorinated hydrocarbons. In addition, ethane can also be oxidized with oxygen at high temperatures to produce carbon dioxide and water.

2. Ethane Uses

1. Fuel
Ethane is a commonly used fuel with high calorific value and clean combustion characteristics. As one of the main components of liquefied petroleum gas (LPG), ethane is widely used in domestic, industrial and commercial fields. In addition, ethane can also be used as fuel for rocket engines.

2. Chemical raw material
Ethane is an important chemical raw material that can be used to produce a variety of chemicals. The following are the main chemical uses of ethane:

(1) Ethylene production: Ethane can generate ethylene through steam cracking reaction. Ethylene is an important basic chemical raw material and can be used to produce polyethylene, styrene and other chemicals.

(2) Ethanol production: Ethane can generate ethanol through hydration reaction. Ethanol is an important organic solvent and chemical raw material, which can be used to produce acetaldehyde, ethyl acetate and other chemicals.

(3) halogenated hydrocarbon production: ethane can be replaced with halogen elemental reaction to generate halogenated hydrocarbons, halogenated hydrocarbons are widely used in solvents, refrigerants, fire extinguishing agents and other fields.

In conclusion, ethane, as an important chemical raw material, has a wide range of applications in the field of chemical production raw materials.
