glykoli

Glykoli is a term that can refer to several different chemical compounds, but most commonly it is used as a colloquialism for ethylene glycol. Ethylene glycol is an organic compound with the formula (CH2OH)2. It is a clear, colorless, odorless, viscous liquid that is miscible with water. Its primary industrial application is as an antifreeze in automotive cooling systems due to its low freezing point and high boiling point. When mixed with water, it significantly lowers the freezing point of the mixture, preventing the engine from freezing in cold temperatures. It also raises the boiling point, helping to prevent the engine from overheating in hot conditions.

Beyond its use as antifreeze, ethylene glycol is also a key component in the production of polyester fibers and resins, widely used in clothing, carpeting, and plastic bottles. However, it is important to note that ethylene glycol is toxic if ingested. Accidental ingestion can cause severe health problems, including kidney damage, and can be fatal. For this reason, it is often dyed a bright color in antifreeze formulations to make it more visible and less appealing to children and pets.

Another compound sometimes referred to as glykoli is propylene glycol. Propylene glycol is also a clear, colorless, odorless liquid that is miscible with water, but it is generally considered less toxic than ethylene glycol. It has a wide range of applications, including as a food additive (E1520), in cosmetics and personal care products, and as a de-icing fluid for aircraft. The specific context in which the term "glykoli" is used is important for determining which compound is being discussed.
