Read： 151 Time：12months ago Source：化易天下

ethylene glycol is a chemical widely used in various industries, and its role and use is very extensive. Ethylene glycol is an organic compound with a chemical formula of C2H6O2. It is a colorless and odorless liquid at normal temperature and pressure. It has good solubility and stability, and is widely used in pharmaceuticals, cosmetics, plastics, printed circuit boards and other industries. Below, we will introduce the role and use of ethylene glycol from many aspects.

1. the role of ethylene glycol in pharmaceutical
ethylene glycol in the pharmaceutical industry is widely used. It can be used as a pharmaceutical intermediate and solvent for the synthesis and extraction of drugs. Ethylene glycol can also be used for the preparation of anesthetic, external medicine, oral solution, injection, eye drops and other products. In addition, ethylene glycol is also an effective antifreeze, which can increase the stability of the drug and extend the shelf life of the drug.

2. The use of ethylene glycol in cosmetics The application of
ethylene glycol in cosmetics is also very extensive. It can be used as a moisturizer, antifreeze, solvent, etc. Ethylene glycol can absorb moisture in the air, keep cosmetics in a moist state, and prevent cosmetics from deteriorating due to dryness. In addition, ethylene glycol can also be used as a solvent for hair dyes, lipstick and other cosmetics.

3. The role of ethylene glycol in the plastics industry
ethylene glycol is also widely used in the plastics industry. It can be used as a raw material for polyester resins for the manufacture of plastic products. Ethylene glycol can also improve the toughness and transparency of plastic products, and will not affect the physical properties of plastics, improve product quality.

4. Application of ethylene glycol in the manufacture of printed circuit boards
ethylene glycol is also used in the manufacture of printed circuit boards. It can be used as a cleaning fluid for cleaning circuit boards and printed boards. The glycol in the cleaning fluid can effectively remove the grease and dirt on the surface of the circuit board and the printed board, making the surface smooth and clean.

In short, ethylene glycol is a very important organic compound with a wide range of applications. From pharmaceuticals, cosmetics, plastics to printed circuit board manufacturing, the role and use of ethylene glycol are very important. With the continuous development of technology and the continuous expansion of application fields, the application prospects of ethylene glycol will be more broad.
