An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH 2 OH) 2.It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations.

Most types of ethylene glycol antifreeze contain a few percent of diethylene glycol, present as a by-product of ethylene glycol production. DEG is an important industrial desiccant . It absorb water from natural gas , minimizing the formation of methane hydrates , which can block pipes.
Boiling point: 188.2 °C (370.8 °F; 461.3 K) ... Manufacturers use either non-catalytic high-temperature process at 200 ... or antifreeze solutions for emergency eye ...
Water boils when it reaches its boiling point of 212 degrees Fahrenheit, 100 degrees Celsius or 373 degrees Kelvin. Cold water does not boil faster. Water boils when it reaches its boiling point ...
Triethylene glycol is a member of a homologous series of polyethylene glycols.It is a colorless, odorless and stable liquid with high viscosity and a high boiling point. . Apart from its use as a raw material in the manufacture and synthesis of other products, TEG is known for its hygroscopic quality and its ability to dehumidify fl
The minimum freezing point temperature is about −38 °C (−36 °F) corresponding to 70% glycerol in water. Glycerol was historically used as an anti-freeze for automotive applications before being replaced by ethylene glycol, which has a lower freezing point.
