What is C6H14O4 called?
Triethylene glycol (also known as TEG, triglycol and trigen) is a colourless, viscous, non-volatile liquid with the formula C6H14O4. It is well known for its hygroscopic quality and its ability to dehumidify fluids.
What is triethylene glycol?
Triethylene glycol also known as triethylene glycol, triethylene glycol, triethylene glycol diethylene glycol. Colorless, odorless, hygroscopic, viscous liquid. Miscible with water and ethanol, slightly soluble in ether.
Is C6H14O4 an alcohol?
Antifreeze Properties of Triethylene Glycol
Triethylene glycol lowers the freezing point of water when mixed into aqueous solutions, which gives it antifreeze capability. Compared with water alone, TEG–water mixtures remain fluid at lower temperatures and provide good thermal stability.
C6H14O4 Properties
- Freezing point depression when mixed with water
- High boiling point (~288 °C), reducing vapor loss at elevated temperatures
- Low volatility, improving safety and handling
- Good thermal stability for continuous circulation systems
Triethylene glycol Storage Conditions
To ensure the quality and stability of triethylene glycol, proper storage conditions are crucial. The following are the recommended storage conditions for triethylene glycol:
- Temperature: Triethylene glycol should be stored at room temperature (15-25℃), and should not exceed 30℃. High temperatures can easily decompose triethylene glycol, reducing its quality.
- Humidity: Triethylene glycol should be stored in a dry, well-ventilated environment, avoiding moisture. High humidity can cause chemical reactions in triethylene glycol, affecting its quality and efficacy.
- Light: Triethylene glycol should be protected from prolonged exposure to sunlight or other strong light sources. Ultraviolet rays in sunlight can degrade triethylene glycol, affecting its stability.
In addition to the above storage conditions, the following should also be noted:
- Avoid contact with free acids or acidic substances to prevent decomposition reactions.
- Avoid contact with alkaline substances to prevent gel precipitation.
- Storage containers should be colorless, odorless, and non-toxic glass bottles or polyethylene plastic bottles to avoid contamination or decomposition.
