The role of diethylene glycol

1, mainly used as gas dehydrating agent and aromatic extraction solvent.

2. It is also used as a solvent for nitrocellulose, resin, grease and printing ink. It is a softener and finishing agent for textiles. It is used to extract coumarone and indene from coal tar.

3. In addition, diethylene glycol is also used as brake oil compounding agent, celluloid softener, antifreeze and diluent in emulsion polymerization.

4. Also used as plasticizer for rubber and resin; Polyester resin; Glass fiber; Polyurethane foam; Production of lubricating oil viscosity improver and other products.

5. Used for synthesizing unsaturated polyester resin, plasticizer, etc.

6. It can also be used as antifreeze, gas dehydrating agent, plasticizer, solvent, aromatic hydrocarbon extractant, cigarette hygroscopic agent, textile lubricant and finishing agent, paste and anti-drying agent of various adhesives, and hygroscopic cosolvent of vat dyes.

7. It is a common solvent for oil, resin and nitrocellulose.
