Please clarify. To 'dry' means to remove water, acetone contains no water; it is used to remove water from other mixtures. If you mean to remove acetone, it evaporates rapidly at room temperature and very quickly when heated under flashpoint. The liquid and vapor are both dangerous to humans and animals and should not be dealt with indoors and/or near open flame (such as pilot lights).

Try silica gel. It absorbs three times it own weight in water and is non-toxic. It can also be regenerated.

Actually acetone does contain very small amounts of water and alchol, if you are using it to wash or purify a chemical then you will want to get rid of the water and the alcohol. This can be done buy getting some epsom salts, spreading them on a tray, and baking them for 2hours at 400 degrees, then scrape up 10 grams, put it into 1 litre of acetone, shake well, and let sit for 24 hours, the salt will sink to the bottom... and it is now anhydrous acetone (no water or alcohol)... hope this helps

To dry acetone you must use Molecular Sieves size 3A. Check out pnjresources.com Once it is dry you have to keep it in something air tight as it is slightly hygroscopic. AN
