Ethylene is an important raw material for chemical production, which has a wide range of properties and uses. In this paper, the properties and uses of ethylene will be discussed in detail.
1. Properties of Ethylene
Ethylene is a colorless, flammable, slightly sweet-tasting gas with the formula C2H4. It has the following properties:
1. Insoluble in water, but soluble in organic solvents.
2. Ethylene is an important chemical raw material because its carbon-carbon double bond makes it easy for addition reaction.
3. Ethylene has a slightly smaller density than air and is hardly soluble in water.
2. the use of ethylene
ethylene as an important chemical raw material, widely used in various fields, the following are its main uses:
1. polymerization reaction: ethylene can be polymerized to produce polyethylene, polyethylene is a widely used plastic material, used in the manufacture of various daily necessities, packaging materials, pipes, wires and cables.
2. Ethanol production: Ethylene can react with water to produce ethanol. Ethanol is an important organic solvent and chemical raw material, and is also used in the manufacture of beverages and fuels.
3. Manufacture of vinyl chloride: the reaction of ethylene and chlorine can generate vinyl chloride, vinyl chloride is the raw material for the manufacture of polyvinyl chloride, polyvinyl chloride is widely used in the manufacture of various plastic products.
4. Production of acetaldehyde, acetic acid and other chemicals: Ethylene can also be further oxidized to produce acetaldehyde, acetic acid and other chemicals, these chemicals are the raw materials for the manufacture of many important chemical products.
3. Ethylene Production
There are two main methods for
ethylene production: steam cracking and ethanol dehydrogenation. Steam cracking is the process of cracking petroleum hydrocarbons to produce ethylene under high temperature and high pressure, and is the main method of industrial production of ethylene. Ethanol dehydrogenation is a process of dehydrogenation of ethanol to ethylene under high temperature and high pressure.
4. the safety
of ethylene
ethylene is an important chemical raw material, but its harm to human body can not be ignored. Long-term exposure to ethylene may cause dizziness, headache, nausea and other symptoms, and even lead to coma and death in severe cases. Therefore, in the process of production and use, it is necessary to strictly abide by the safety operation procedures to ensure the personal safety of the staff.
5. Ethylene Market Prospect
With the progress of science and technology and the development of chemical industry, the market demand for ethylene is showing a growing trend. In the future, with the continuous expansion of new energy, new materials and other fields, the market prospect of ethylene will be broader.
In short, ethylene, as an important raw material for chemical production, has a wide range of properties and uses. In the future development, we need to continue to study the nature and use of ethylene, continuously improve its production efficiency and use safety, and make greater contributions to promoting the sustainable development of the chemical industry.
