Glükoolilahus

Glükoolilahus refers to a solution containing glycol. Glycols are a class of organic compounds characterized by the presence of two hydroxyl groups. The most common glycol used in solutions is ethylene glycol, also known as monoethylene glycol (MEG), or propylene glycol, also known as 1,2-propanediol. The specific properties of a glükoolilahus depend on the type of glycol, its concentration, and the solvent, which is typically water.

These solutions have a variety of applications. Ethylene glycol-based solutions are widely used as antifreeze in automotive cooling systems due to their ability to lower the freezing point and raise the boiling point of water. This prevents the engine from overheating in summer and freezing in winter. Propylene glycol solutions are also used as antifreeze, particularly in applications where toxicity is a concern, such as in food processing equipment or as a de-icing fluid for aircraft.

Beyond antifreeze, glükoolilahus finds use in other areas. They can act as heat transfer fluids in industrial processes, solar thermal systems, and geothermal heating and cooling systems. In some industrial settings, they serve as solvents or humectants. The selection of a specific glycol and its concentration is determined by the required performance characteristics and safety considerations for the intended application. It is important to note that ethylene glycol is toxic if ingested, while propylene glycol is generally considered less toxic.
