Etilenoglicoledietileno glicolsão ambos produtos químicos industriais importantes, mas eles têm várias diferenças distintas .
Estrutura química
- Ethylene glycol has a simple structure with two carbon atoms, each bonded to a hydroxyl group (-OH), and its molecular formula is C₂H₆O₂. Diethylene glycol, on the other hand, contains four carbon atoms, with two hydroxyl groups at each end, and its formula is C₄H₁₀O₃. The additional carbon - oxygen chain em dietileno glicol, fornece uma estrutura mais complexa .
Propriedades físicas
- These two substances also vary in physical properties. Ethylene glycol has a lower molecular weight, resulting in a lower boiling point of 197.3℃and a higher freezing point compared to diethylene glycol. Diethylene glycol, with its more complex structure, has a higher boiling point, usually around 245℃, and better solubility in some solventes orgânicos.
Aplicações
- In application, ethylene glycol is mainly used as a key component in antifreeze due to its effective freezing - point - lowering ability. It is also crucial for producing polyester fibers and plastics. Diethylene glycol, however, serves as a solvent in paints and inks, a plasticizer in polymers, and is used in pharmaceuticals and Cosméticos por suas propriedades umectantes .
Segurança
- Both can be harmful if ingested, but diethylene glycol is more toxic. Accidental ingestion of diethylene glycol can cause severe kidney damage and even death. In contrast, while ethylene glycol is also toxic, the different toxicity levels mean that safety precautions and regulatory controls around their use differ significantly.
