...freeze DIETHYLENE GLYCOL?

Melting point is -10.45C, so yes, and it's not even that cold...

List of physical properties here. Note that the pour point is far below the listed freezing point, which doesn't seem to make a lot of sense.

Thanks for the quick responce.

-9 degree's is pretty darn cold. Colder than a household freezer.

Should there be a medium introduce like water to help it freeze at a higher temperature?

It lowers the freezing temp of water. So adding water will not speed up the process.

Not concerned in speeding up the process.

Concerned on the part of freezing.

Curious to know if there is a way to freeze DEG without going to the -9 degree envelope.

What about petroleum hydrocarbons??

Why? You looking to get peripheral neuropathy?

I am looking for cause and effect.

EFX.

Should I get dry ice to get to the -9 degrees to freeze the DEG?

i would think you'd need to get colder than that tho

-9Â°C is equivalent to +16Â°F. Not very cold at all. A household freezer will normally be at about 0Â°F, or about -18Â°C.

Edit:
Also, mixtures of substances often cause their freezing temperatures to fall (and their boiling points to rise). Reference this page for pertinent info on freezing point of ethylene glycol/water mixtures.

Thanks.

Just found out dry ice is my answer.

It freezes down to -110 F degrees.

All I need is -9 F degrees.

Problem solved.

You also need to keep the glycol very dry. It will pick up moisture from *everywhere* including exposure to the air. Any moisture will drop the freezing point.

Edit: If you're using dry ice, it will freeze no matter the water content. Very pure DEG will freeze at +16Â°F, so even a household freezer will do just fine.

The Freazing point for Canadians. Just kidding, I love Canada. No Actually, I am dying of curiosity myself.

i've had a look at what it is and here is the pertinent question:

Why, if you have this stuff and are not part of industry (because if you were you would know how to and if you could freeze it), do you need to know how to freeze it? :-S

Ease of transportation... fine... but why have you got it in the first place?

also, a quick look at uses and stuff on wikipedia is rather alarming because the stuff is responsible for poison outbreaks which have killed many people. I might be alarmist in saying this but what you are asking is akin to asking how to make a pipe bomb...

It also is used for warming trays.

You know, those little cans that are under tin foiled pans, that keeps food warm.

I think there is enough alarmists in the world, none needed here please.

As far as WHY I need to know, you will just have to stay tuned.
