What is the chemical name for antifreeze?
Actually, antifreeze will freeze. It just freezes at a much lower temperature than ordinary water. But it can freeze, and the chemical structure of antifreeze is such that the molecules will not change state (liquid to solid -- freeze) except at the very lowest temperatures. A lot of thermal energy must be removed from antifreeze to cause the molecules to "hook up" and the stuff to change state into a solid. It's based on the…
Jaguar REQUIRES an "Aluminum Safe formulation", and my local Jag mechanic recommends a chemical/pressure flush every 2 years. Any high quality, name brand that is marked as "Safe for aluminum" is sufficient. A chemical reaction can occur inside the coolant system with low quality antifreeze/coolant which can cause corrosion and pitting of aluminum components. The "purple" antifreeze is aluminum safe and non-toxic to prevent injury to you family pets should a leak develope.
Common antifreeze contains the chemical that makes antifreeze work which is Ethylene Glycol (ethane-1,2-diol)that has a freezing point of below 12.9 degrees Centigrade when added to water, it lowers the freezing point of water dramatically it is currently made by the hydration of ethylene oxide in industries other chemicals are mainly water chemicals and maybe even some dyes.
