3A Zeolite
https://www.ebay.ca/itm/Difantool-Molecular-Sieve-Zeolite-3A...
Ordered two hundred grams, arrived in good condition quality packaged.
Messaged about regen temp, promptly responded with operating temp and regen temp.
Thought I'd share.

Regen temp: 180c to 500c, recommended 350c
Operating: 0c - 38c recommended 8c-12c
Fore these particular ones.
Going to vacuum dry in a 500ml flask and monitor via thermal couple, via claisen adapter and vacuum take off fitting. Monitor end point via vacuum
micron gauge.

Well the packaging certainly is good quality, hermetical sealed Mylar bags with a resealable strip in them. Very vague on instructions though, so I
had to contact them, for the 3A variant the specs are up top.

Figured I'd show the alcohol I use and the steps to purify it
this is the type, they use Ethyl Acetate as the denaturent and that's it, in low concentrations too.
![Alcohol source.jpg - 256kB](http://www.sciencemadness.org/talk/files.php?pid=615878&aid=76026)
So Step one (No pics sorry) Reflux over Sodium Hydroxide for a few hours, then distill, this is what you're left with:
![Purifying Alcohol 1.jpg - 231kB](http://www.sciencemadness.org/talk/files.php?pid=615878&aid=76028)
Then you repeat with fresh Hydroxide, you'll see the distillate tailings is much cleaner
![Second purifying run.jpg - 196kB](http://www.sciencemadness.org/talk/files.php?pid=615878&aid=76030)
Distill again and then dry over Magnesium Sulfate, Anhydrous (Sorry forgot to take pics), then filter off to fresh dry flask.
![Purifying Alcohol 2.jpg - 177kB](http://www.sciencemadness.org/talk/files.php?pid=615878&aid=76032)
Now for the part you where all expecting: Add your Molecular sieves and let stand till needed!
![Final drying 2.jpg - 178kB](http://www.sciencemadness.org/talk/files.php?pid=615878&aid=76036)
To regenerate I will heat in a flask with a condenser attached to recover any ethanol that comes off, then once that stops will continue to heat under
vacuum to regen temp
