1. Solvent: DEG is a good solvent, can be used for tank cleaning, pigment and dye preparation and other processes. It can dissolve a variety of organic compounds, which helps in the process of reaction and mixing of substances.

2. Coolant and antifreeze: Similar to chemical ethylene glycol, diethylene glycol can also be used as engine coolant and antifreeze. It has a low freezing point and a high boiling point, which can prevent the coolant from freezing at low temperatures and prevent the car engine from overheating at high temperatures.

3. Plasticizer: diethylene glycol can be used as a plasticizer for plastic and rubber products to improve their softness, toughness and ductility. It can improve the properties of polymers, making them more suitable for a variety of applications.

4. Lubricant: Because diethylene glycol has low viscosity and good lubrication performance, it can be used as a lubricant to be added to various mechanical equipment and industrial systems to reduce friction and wear.

5. Medicine and cosmetics: Diethylene glycol can be used as an ingredient in medicines and cosmetics. It can be used as a solvent, stabilizer and moisturizer in the preparation of oral solutions, injections and skin care products.
