Diethylene glycol

Diethylene glycol, also known as dihydroisopropanol, is a colorless liquid soluble in most organic solvents with a weakly sweet taste. Below is an introduction to the properties, uses, production methods, and safety information of diethylene glycol:

Properties:

2. Chemical Properties: Diethylene glycol is a stable compound, resistant to air and water. It can react with many organic compounds, such as anhydrides, aldehydes, ketones, etc.

Uses:
1. Industrial Applications: Diethylene glycol is widely used in industries such as pharmaceuticals, coatings, plastics, resins, rubber, solvents, dyes, and inks, serving as a plasticizer, antifreeze, solvent, wetting agent, adhesive, etc.


Production Methods:
There are two main methods for producing diethylene glycol:
1. Isopropanol Oxidation Method: Diethylene glycol is obtained by reacting isopropanol with a cesium monoxide catalyst, followed by an oxidation reaction.
2. Propylene Oxide Hydrolysis Method: Diethylene glycol is produced by reacting propylene oxide with water.

Safety Information:
1. Diethylene glycol is somewhat toxic to humans and may cause poisoning with long-term exposure. Inhalation or skin contact should be avoided.
2. Safe operating procedures should be followed during use, such as wearing protective gloves, goggles, and protective clothing.
3. Storage requires tight sealing, away from fire sources and oxidizing agents.
4. In case of accidents or leaks, appropriate emergency measures should be taken immediately, such as ventilation, isolating the leaked material, etc., to prevent spread and reduce harm.
