High purity ethylene, as an important organic compound, is one of the indispensable basic raw materials in the chemical industry. Its chemical formula is C2H4, and its structural formula is CH2=CH2, which belongs to olefin compounds. Ethylene molecules contain carbon-carbon double bonds. This special chemical structure gives it unique chemical properties, such as easy addition reactions and oxidation reactions. At room temperature and pressure, ethylene is a colorless, slightly odorous gas that is difficult to dissolve in water but easily soluble in organic solvents. Due to its active chemical properties, ethylene is widely used in many fields such as chemicals, plastics, rubber, and textiles.
The industrial production of ethylene mainly depends on the petroleum cracking process, which heats the petroleum hydrocarbon mixture to a high temperature to crack it into small molecular hydrocarbons, including ethylene. This process not only requires high-precision process control, but also has a certain impact on the environment. Therefore, in the production and use of ethylene, environmental protection and sustainable development have become important issues.
Overview of the application of ethylene in the chemical field
As an important raw material in the chemical industry, ethylene has a very wide range of applications. In the plastics industry, ethylene is the main raw material for the production of polyethylene (PE), which is a widely used plastic material used in packaging, construction, wires and cables and other fields. In addition, ethylene can also be used to produce other types of plastics such as polyvinyl chloride (PVC) and polystyrene (PS).
In the rubber industry, ethylene and propylene and other monomers can be copolymerized to produce ethylene-propylene rubber, which has excellent aging resistance, oil resistance, corrosion resistance and other characteristics, and is widely used in automobile tires, conveyor belts, seals and other products. At the same time, ethylene can also be used to produce other types of rubber such as styrene-butadiene rubber and butadiene rubber.
In addition to the plastics and rubber industries, ethylene also plays an important role in many fields such as textiles, chemical fibers, pesticides, and medicines. For example, ethylene can be used to produce chemical fiber raw materials such as ethylene glycol and ethanolamine; it can also be used to produce pesticides such as ethephon; in the field of medicine, ethylene derivatives such as vinyl acetate are also used as raw materials for drug synthesis.
