Pros of Using Water Instead of Antifreeze In an emergency, it is still better to put water in your radiator than driving without ANY kind of liquid, even it is better than driving with very low levels of it. The engine would overheat in this situation, and the consequence would be huge damage to many car parts.
Antifreeze lowers the freezing point of any liquid to which it is added by preventing ice crystals from forming properly. Propylene glycol is completely soluble in water and it has the feature of dissolving many organic compounds such as fragrances, essential oils and resins and in addition, it has extremely low toxicity and is virtually harmless to the human body.
Ethylene glycol is completely miscible with water in all proportions as the commenters point out. Therefore, once mixed, the glycol will not separate from the water, ever.
The only exception is if it gets so cold the mixture starts to freeze. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Skip to content 1 Answer. Additional Questions Does propylene glycol absorb water?
How do you dissolve polyethylene glycol? Can I mix antifreeze with tap water? Yes, it is used as one of the two starting materials used in the manufacture of polyethylene terephthalate PET, a.
The diacid terephthalic acid benzene-1,4-dicarboxylic acid reacts with the diol ethylene glycol forming the polyester. This has many uses, one being to make plastic soft-drink bottles which may be used to incorrectly store antifreeze.
Others include insulation and wrapping; ropes; carpets and clothing. Over 20 million metric tonnes of ethylene glycol are manufactured each year. It can be converted into several other useful chemicals, like glyoxal, glycolic acid and methyl glycolate, and other uses continue to develop, including the synthesis of nanomaterials.
In the liver, the enzyme alcohol dehydrogenase converts ethylene glycol first into glycoaldehyde and then into other toxic molecules. Ultimately oxalic acid removes calcium from the body as insoluble calcium oxalate, which is deposited in the kidneys and damages them, leading to renal failure.
Methanoic formic acid is also generated, which can cause blindness. Because antifreeze is such an everyday chemical, some people get careless with it around the home. They store it in containers meant for other things, like containers meant for drinks — and not correctly labelled. People leave it around on garage shelves where children can find it. Spills are not always cleaned up. This means that pets and small children are especially at risk. A spoonful or so can be fatal to a cat or small dog.
The lethal dose for an adult human is around grams. Antifreeze usually is brightly coloured and the ethylene glycol gives it a sweet taste, making it attractive to young people. In some places a bitter tasting substance like denatonium benzoate is added to it to put people off, but some research has suggested that this is not successful.
