ethylene glycol;glycerol;propane-1,2-diol(CAS: 9082-00-2)

Ethylene glycol (CAS: 9082-00-2) is a colorless, viscous, sweet-tasting liquid with a slight odor. It has a molecular weight of 62.07 g/mol and a high boiling point of 197.3°C. Ethylene glycol is moderately soluble in water and miscible with ethanol. It is less reactive than water but can still undergo reactions such as oxidation and esterification. It has a specific gravity of 1.111 g/cm³ and a flash point of 151.1°C.

Ethylene glycol (CAS: 9082-00-2) is typically synthesized through the hydration of ethylene oxide. The reaction is catalyzed by acidic or basic catalysts, with sulfuric acid being the most common. The process involves the conversion of ethylene oxide to ethylene glycol with high selectivity and yield, often in the range of 90-95%. An alternative method involves the direct hydration of ethylene, but this is less common and more challenging.

Ethylene glycol (CAS: 9082-00-2) is widely used in various industries. It is a key component in antifreeze and coolant formulations, automotive brake fluids, and as a solvent in the production of polyester fibers and polyurethane. It is also utilized in the manufacturing of polyester resins, brake fluid, and as a humectant in paints and coatings. Additionally, it is used in the electronics industry for cleaning and in sensors as a humidity indicator.

When handling ethylene glycol (CAS: 9082-00-2), it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store it in a cool, dry place away from direct sunlight and heat sources. Use appropriate ventilation and handle it in a fume hood to avoid inhalation. In case of a spill, immediately contain it using absorbent materials and dispose of the waste according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed guidelines on handling and storage.
