Diethylene Glycol (DEG) Product Description**
Product Overview**
Diethylene glycol (DEG), with the chemical formula C4 H10 O3, is a condensation product of ethylene glycol. It is a colorless, transparent, viscous liquid at room temperature, with strong hygroscopicity, high boiling point (245 ºC), and excellent solubility. Its molecular structure contains two hydroxyl groups and two ether bonds, possessing both hydrophilicity and solvent properties. It is widely used in fields such as polyurethane, resin synthesis, antifreeze, textile printing and dyeing, and industrial solvents. Although attention should be paid to its toxicity control (not applicable to food and drugs), it is still a cost-effective functional chemical in compliant industrial scenarios.
