This critical review describes a broad spectrum of properties of EG and significant advances in the prevalent synthesis and applications of EG, with emphases on the catalytic reactivity and reaction mechanisms of the main synthetic methodologies and applied strategies.
The major use of ethylene glycol is as an antifreeze agent in the coolant in for example, automobiles and air-conditioning systems that either place the chiller or air handlers outside or must cool below the freezing temperature of water.
Properties of a 50-50 ethylene glycol-water mixture: Freezing point: Approximately -37°C (-34.6°F). This mixture offers excellent low-temperature protection, helping to prevent freezing in the cooling system.
Water, either purified or deionized, is the most common and efficient coolant used in recirculating cooling systems, making it a standard for comparison to other coolant fluids. Other common coolant types include ethylene glycol, propylene glycol, mineral oil, and dielectric fluids.
14 Οκτ 2022 · Ethylene glycol is a clear, viscous liquid primarily used in industrial manufacturing applications, and is an ingredient in products like automotive antifreeze and coolant. Ethylene glycol is produced by reacting the chemical compound ethylene oxide with water.
26 Σεπ 2024 · Ethylene glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C (388.4 °F). Its most common use is as an automotive antifreeze . A 1:1 solution of ethylene glycol and water boils at 129 °C (264.2 °F) and freezes at −37 °C (−34.6 °F), serving as an excellent coolant in automotive radiators.
