Diethylene Glycol and Ethylene Glycol
Chemical Structure
Diethylene glycol (CAS: 111-46-6) and ethylene glycol (CAS: 107-21-1) differ in chemical structure. The chemical formula of diethylene glycol is HOCH₂CH₂OCH₂CH₂OH, while the formula of ethylene glycol is HOCH₂CH₂OH. They have distinct molecular structures. Diethylene glycol is formed by linking two ethylene glycol molecules through an ether bond. Ethylene glycol does not contain this ether linkage.
Physical Properties
Diethylene glycol (CAS: 111-46-6) and ethylene glycol (CAS: 107-21-1) also differ in physical properties. Ethylene glycol has a higher boiling point and density compared to diethylene glycol, while diethylene glycol has a higher viscosity than ethylene glycol.
diethylene glycol and ethylene glycol uses
Due to differences in chemical structure and physical properties, diethylene glycol and ethylene glycol are used in different fields. Ethylene glycol is widely used in the production of synthetic resins, coatings, solvents, and antifreeze. Diethylene glycol, on the other hand, is mainly used in the production of emulsions, plastics, and flexible foams.
