- Making A Still - For the glasswareImpaired.
-
- Its suprisingly easy to manufacture an operating "still" for distilling
- just about anything. The one described in this file is no doubt of a lower
- grade than great-grandpa used in the 20's to make booze, but will function
- for recovering solvent for any number of reasons. It was successfully used
- to distill acetone from an acetone-containing extract, so that it could be
- recycled. Such policy is good for two reasons - simple evaporation is bad
- for the environment, your lungs, and your neighbors lungs. And the LAST
- thing to EVER want to do is make your neighbors mad at you. After all, they
- live right next to you.
-
- The hardest thing to get to make this still is probably corks with two
- holes in them. Try craft stores. Or make your own holes - try a soldering
- iron then clean the burnt stuff out with a round file. Using a power drill
- will probably NOT work due to the sticky gooey nature of rubber + friction
- + heat.
-
- Ingredients:
- Two rubber corks, one with two holes at least.
- Two "Snapple" jars or other jar that will take a cork.
- NOTE: When using non-pyrex, it is important to avoid quick changes in
- temperature as well as differences in temperatures touching the
- glass. For example, its in extremely poor taste to stick a non-
- heat-safe glass containing a liquid that will boil at 30c into
- an oil bath that will be heated to 120c - even if slowly heated,
- the liquid on the inside won't ever go over 30c, and there will be
- a huge temperature difference between the inside and outsides of
- the glass.
- ALSO: Try and clean the things out good first
- 6 or so feet of aluminum tubing, available at the plumbing store.
- Its probably next to the copper tubing used in hooking water to
- something that will move, like a refridgerator or a water cooler.
- To get aluminum, just make an ecoFreak fuss over copper pipe. Its not
- like your trying to buy a triple neck flask here anyways...
- Electric skillet with temperature control
- This will let you somewhat control the temperature of your heating bath.
- A spark-free or sealed relay is always nice also. Suprisingly, this is
- often the case - but always check first. Probably lawyers trying to
- minimize damages from oil fires caused by innatentive-housewives.
- Sink. Yes, a sink is a good thing.
- A big container to stick ice and a snapple jar into. Salt too, if ya
- need it to cool the ice.
-
- Setup is as follows:

- (use oil if over 100c needed)
-
- Since I had only two-holed corks, I plugged one up. The aluminum pipe can
- be sealed suprisingly good by cutting it, flattening it against itself
- with pliers, then bending it and flattening that again. Conversely, after
- you "cave in" the ending with your metal sheers, pliers are also great for
- carefully squeezing the hole back open.
-
- There are certain obvious rules to use with this setup:
- 1. Dont distill anything that will release acidic vapors. Aluminum pipe is
- NOT the place to condense your acetic anhydride supply.
- 2. Try to avoid strain that will pop the corks back out. This is simply
- enough with aluminum piping.
- 3. Avoid kinks in the aluminum piping.
- 4. Dont let the stuff boil so much that bubbleChunks float up and get
- "sucked" into the pipe
- 5. Add fresh ice to the still as you make progress.
- 6. When working with ANYTHING other than water, no flames, even if there
- is no odor, which there likely wont be (!!!). When working with stinky
- acetone containing Aromatherapy Oils, which are by nature smelly, I did
- not smell either until I uncorked the heating vessel!
- 7. Uncork as soon as boiling stops, to prevent backwash. This is doubly
- important if the input to the cooling vessel reaches below the surface
- of the condensed solvent.
- 8. Always label recycled solvent as such, and try to reuse it for "the same
- purpose" for obvious reasons. For example, most solvents are no longer
- going to be anhydrous after this unless further processed.

- What about solvent vapors that dont condense???
- Build POPeye's "stench tube".

-
- POPeye calls this beast a "stench tube". Its lowered into the sink, and
- running water carries any vapor that might not condense into the sewer
- systems. Its not 100% foolproof, but its probably a hell of a lot safer
- than sending it coursing thru the local ecoFreak's ventilation systems...
- Try not to backwash water into your solvent.
