Acetone ?

[Big Inhale]

Can you freeze precip acetone or do you have to evap for a recrystallization.

You can't freeze precipitate in it.

Thank you. is it a quick evap or slow.

apply some heat and a fan and it will evap in no time...its best to keep it slightly warm though because it evaporates so quickly that it will chill the container you are evaporating it in..and cause water to condense on it..which you dont want..so keep it warm and use a fan..it will be gone in less than 20 minutes...depending on the quantity..but it will stink

In step 6 of the harmine crystals from syrian rue tek that is in the Wiki can swim substitute acetone for the methyl/ethyl alcohol.

SWIM has done an evap test on his new acetone, that wasn't the cheapest because it was meant to be 'pure'.

The annoying stuff left a dark yellow ring around the white cup he did it in, and a similar puddle stain in the bottom.
SWIM then tested some old acetone that he's had for 5 years, and that stuff also left a yellow stain, but less than the 'pure' stuff!

Argh! This is postponing important experiments! Is this normal for acetone?

SWIM is doing his tests in little china coffeecups. He's sure he cleaned them to a sparkly white before the evap tests so he doesn't think it's tea residue.

I don't know. Sorry didn't mean to hijack your thread, I just didn't think mine wasn't enough of a question for its own thread so I put it in yours.

Somebody help us!

Please help. Someone.

I don't know if you can use acetone instead of methyl/ethyl alcohol. But denatured alcohol (which is ethanol with some methanol added to it) is pretty easy to get. Just go to an Ace or Home Depot and they should have quart to gallon sized containers. (I know this doesn't really answer the question but I thought it might be helpful).
