What is another name for ethylene glycol?
ethane-1,2-diol
ethylene glycol, also called ethane-1,2-diol, the simplest member of the glycol family of organic compounds. A glycol is an alcohol with two hydroxyl groups on adjacent carbon atoms (a 1,2-diol).
What is ethylene glycol used for?
DESCRIPTION: Ethylene glycol is a useful industrial compound found in many consumer products. Examples include antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics. It can also be a pharmaceutical vehicle.
What is ethylene glycol antifreeze?
Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant. Ethylene glycol helps keep your car’s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer.

Is ethylene and ethene the same?
Ethylene is the most produce compound in organic chemistry. Ethylene (also called Ethene; C2H4), the simplest Alkene, is an organic compound containing a C=C double bond. Ethylene is a coplanary unsaturated hydrocarbon (also called olefin) which is the most produced for industrial use.
What’s the difference between propylene glycol and ethylene glycol?
The main difference between propylene glycol and ethylene is the level of toxicity. Propylene glycol has a very low toxicity, which is why it is also found in cosmetics and personal care products, whereas ethylene glycol is poisonous and must be handled with caution to restrict any human or animal exposure.
Is ethylene glycol the same as antifreeze?
Though coolant and antifreeze are often used interchangeably, they aren’t the same. Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling systems of all “water-cooled” vehicles.
Why is ethylene glycol viscous?
Ethylene glycol is more viscous than ethyl alcohol because ethylene glycol contains two O-H groups (ethyl alcohol contains one O-H group). This results in stronger hydrogen bonding between ethylene glycol molecules.
Is ethylene glycol more viscous than water?
It’s also the increased number of hydrogen bonds in ethylene glycol that makes it more viscous (less runny) than ethanol (or water). Water also contains O-H groups, of course, which ‘hydrogen bond’ to each other, causing water to have a very high boiling point for a molecule of its size.
Ist Ethylenglykol gesundheitsschädlich?
Dabei wird die elektrische Leitfähigkeit des Kühlmediums nicht signifikant gesteigert, da durch das Ethylenglykol keine Ionen gebildet werden. Ethylenglykol ist als gesundheitsschädlich eingestuft.
Wie hoch ist die Viskosität von Ethylenglycol?
Ethylenglycol besitzt bei 20 °C eine Viskosität von 20,81 mPas. Bei 30 °C sinkt die Viskosität auf 13,87 mPas. Bei Verwendung als Kühlflüssigkeit schwankt die Wärmekapazität je nach Wasserzusatz von 2,4 bis 4,2 kJ/ (kg·K) für reines Wasser.
Was ist der Unterschied zwischen reinem und Glykol?
Glykol wird als Frostschutzmittel eingesetzt. Allerdings hat es hier den Nachteil, dass die spezifische Wärmekapazität deutlich unter der von Wasser liegt. Es ist also ein deutlich größerer Volumenstrom des Glykol-Wasser-Gemisches nötig, um die gleiche Wärmemenge wie mit reinem Wasser zu transportieren.
