Junk from "Best organic compounds for crystallization"


Maybe this is not a pure chemical compound, but i would like to see gasoline crystallized. Also other common stuff or compounds like urine, acetone, MEK, oils... Nobody ever done it probably :o

They have.
Obviously, for something like gasoline, or urine which isn't a single compound, crystallisation is a bit meaningless.
Medical + clinical laboratories store urine samples frozen.
So, that gets "crystallised" thousands of times a day.
Frozen urine looks pretty much like you expect from the old joke.

I never froze gasoline, but I have frozen isooctane.
It looks like ice.

Well, I mean pure large crystall. Or less large crystals. Not just small particles and solid, it's too boring. But very very large crystals or single crystal. Any common stuff: food, blood, water. Yeah, water, I think I've never seen water crystal. Don't tell me about ice, it's crystals are either too small, or it's simply whole mass of solid.

Edit: Oops, I forgot, water is inorganic :(

You can't get a single crystal of a mixture. That's nonsense. If you manage to crystallize anything, it will be a mixture of crystals of the individual components.

Snowflakes are water crystals.

Why not try it ?

Until very recently i did not know that a seriously hygroscopic material, CaCl2 could be crystallised.

Turns out that it can, easily.

You sound curious. Because some dark forces are preventing me, whatever that means.

" I mean pure large crystall. "
How do you have a pure mixture?
"I think I've never seen water crystal."
Does it snow where you live?
