I have a bottle of SEALED Glacial Acid Acid - it has begun to crystalize! Has anyone seen this before? It has NOT been exposed to extremes in temp or
UV. The crystals are large and infused within the solution. What's happening?
Is there any method aside from the ketone process to create Acid Anhidryde?

GAA freezes at a "high" temperature. You are merely observing its namesake, why people thought it was "glacial" (ice-like)
despite resembling water (un, in color, viscosity, ...? I've never played with it).

Check out its melting point.

I guess the relatively "high" freezing/melting point of 16.6 C (according to the MSDS I found) and in addition to the sealed nature of your
GAA has caused it to begin to "freeze"

That would be correct just warm it up a bit to melt the crystals

In other words, if you want to avoid this problem, don't store your glacial acetic acid in your garage if you live north of the mason-dixie line.

I keep mine next to the water heater where it is nice and toasty.
It is the
only chem I keep indoors. It does form pretty crystals.

If it does freeze, just leave it out in a warm room and it will melt and should be perfectly useable. Although having crystal of it would be
convenient since they're easily massed . This reminds me of the bottle of
decane sitting in the lab...some days I'll walk in and it's a liquid, other times its a solid, and once, it was either freezing or melting.
