Yes, glycol is commonly used as antifreeze. Ethylene glycol and propylene glycol are two types of glycol widely utilized in antifreeze formulations. They work by lowering the freezing point of the liquid in which they are mixed, preventing it from freezing under cold temperatures. This property makes glycol essential in automotive and industrial cooling systems to protect engines and machinery from freezing and overheating. Chemical Iran offers high-quality glycol products suitable for antifreeze applications. Their ethylene glycol and propylene glycol products are known for their purity and effectiveness in maintaining optimal operating temperatures. By providing reliable glycol solutions, Chemical Iran ensures that vehicles and equipment perform efficiently and safely in various temperature conditions.
Antifreeze is typically made from a mixture of ethylene glycol or propylene glycol, water, and corrosion inhibitors. These substances help regulate the freezing and boiling points of the liquid, protect against corrosion, and prevent overheating in a vehicle's engine.
Ethylene glycol (IUPAC name: ethane-1,2-diol; Chemical formula C2H6O2) is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure form, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is toxic, and ingestion can result in death.
Read Haynes 1993-2004 Antifreeze/cooland - general information: Warning 1: Use only "ethylene-glocol" (green/blue). Do NOT use propylene-glycol (yellow/red). From 2002 long-life-special-glycol (HOAT) are used, and can not be mixed with other types of antifreeze.
Phosphate-free ethylene glycol coolant mixed 50/50 with water
'Regular' or 'traditional' ethylene glycol antifreeze with silicate type corrosion inhibitors (sometimes called green antifreeze) mixed 50% with distilled water is the OE fill.
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
Well, when mixed in an ideal solution with water, it has a relatively high boiling point and low freezing point. Also, it doesn't cause rust/corrosion.
A Ethylene glycol antifreeze coolant should be used (Mopar coolant) and mixed with 50/50 with distilled water. Another coolant that is pretty good is the Zerex G-05 antifreeze (approved by Daimler-Chrysler).
To calculate the mass of propylene glycol needed, we can use Raoult's law. Given that the vapor pressure of pure water at 40 degrees Celsius is 55.3 torr and the desired vapor pressure when mixed is 2.88 atm, we can calculate the mole fraction of propylene glycol needed. From this, we can find the mass of propylene glycol required to achieve this mole fraction when combined with 0.34 kg of water.
Read the owner's manual and buy any antifreeze that meets the requirements listed. The manual calls for Ford Premium Cooling System Fluid, but any water/ethylene glycol based antifreeze solution should be OK. Use the regular green antifreeze, mixed at least 50/50 with water, but never over 70% antifreeze, or just buy it pre-mixed. Make sure it is safe to use with aluminum engine parts. I use Prestone.
A mixture with at least 30% glycol will prevent freezing in most typical applications. The exact percentage needed can vary depending on the specific conditions and requirements of the system. Typically, a higher percentage of glycol is used for lower temperature protection.
