Organic Anti_Freeze

PDD

Hi Guys,

I was just wondering if people know if there is an organic anti-freeze for cars on the market. I presume there are a few out there that would be based on the principle of simply adding ethanol to the water to lower the freezing point?

You need corrosion inhibitors too since the coolant in almost any modern car will come into contact with a few different metals. Some coolants may have stuff in them too to help heat transfer ( eg google waterwetter ) .

The only other alternative i know of would be Propylene glycol, it's a non toxic organic compound chemically similar to regular antifreeze (ethylene glycol) though both compounds are biodegradable.

Any antifreeze used in the cooling system of an engine should be disposed of properly in a recycling center, this is because used antifreeze contains alot of heavy metals such as lead making them hazzardous to your health. (lead is traditionally used to make car radiators)

Using an ethanol water mix would be horribly ineffective, (alcohol has a boiling point quite a bit lower than water as is a very good solvent! eek!) causing alot of corrosion of the aluminium components of an engine, modern engines are primarily made from cast aluminium (what modern antifreeze is designed to help protect) so not good.

So the organic equivalent is Propylene glycol but after being used in an engine it becomes toxic anyway, hope that helps
