properties of ethylene glycol-water mixtures

Ethylene_glycol

Ethylene glycol (monoethylene glycol (MEG) IUPAC name: ethane-1 2-diol) is an alcohol with two -OH groups (a diol) a chemical compound widely used as an automotive antifreeze In its pure form it is an odorless colorless syrupy liquid with a sweet taste Ethylene glycol is toxic and its accidental ingestion should be considered a medical emergency

Propylene Glycol based Heat

For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water The most common antifreeze fluid - ethylene glycol - must not be used where there is a chance of leakage to potable water or food processing systems In food processing systems the common heat-transfer fluid is based on propylene glycol
