Diethylene glycol (Diethylene Glycol, DEG) is a widely used chemical raw material, mainly used in the production of plastics, fibers, resins, antifreeze, solvents and so on. Diethylene glycol also plays an important role in the production of drive materials. This article will discuss the upstream and downstream related products of diethylene glycol-start-up materials.

Upstream Products:

1. Ethylene: Ethylene is the main raw material of diethylene glycol. Ethylene glycol is generated through oxidation reaction, and then further dehydrated to form diethylene glycol.
2. Oxygen: Oxygen, as an oxidant, participates in the oxidation reaction of ethylene to produce ethylene glycol.

downstream products:

1. Driving material: diethylene glycol is one of the main components of the driving material, which helps to improve the viscosity and lubricity of the driving material and protect mechanical parts.
2. Polyester resin: diethylene glycol reacts with dibasic acid to produce polyester resin, which is used in the production of coatings, adhesives, etc.
3. Antifreeze: Diethylene glycol has a lower freezing point and can be added to automobile coolant, aviation hydraulic oil, etc. as an antifreeze to prevent freezing at low temperatures.
4. Solvent: diethylene glycol has good solubility and can be used as a solvent for the production of inks, dyes, etc.

Through the above analysis, we can see the important position of diethylene glycol in the field of chemical production raw materials, and its upstream and downstream related products are widely used in various fields. At the same time, the production and use of diethylene glycol also need to take into account factors such as environmental protection and safety, and follow relevant regulations and specifications to ensure product quality and safety.

In short, as an important raw material for chemical production, diethylene glycol has a wide range of upstream and downstream related products, which is of great significance for promoting the development of various fields. In the future development, we need to continue to deepen the research on the properties and applications of diethylene glycol, improve production technology and product quality to meet the growing market demand, and also need to pay attention to environmental protection and safety issues to promote the sustainable development of the chemical industry.
