disposable ghetto condenser

After looking at these condenser plans: Post 28988 (missing) (simonsays7: "Home made reflux condenser", Chemicals & Equipment)

I was curious as to whether or not a 2 liter Pepsi bottle, with a hole cut in each end the same size as SWIM's cook hose, then filled with ice, slid onto the hose before the reaction vessel was clamped in place, and then duct taped on to prevent water leakage would be an acceptable contraption to use as a condenser.  When SWIM is done with it, just toss the whole shooting match into the burn barrel and be done with it.  No paraphernalia laying about and no fragile glass for SWIM to trip over and break with his big ol' feet.

Is this idea a keeper or not?

ampdup:
Spoke with someone who says dwarfer has already attemped this, and it worked but was heavy and water condensed from the ice melting which sounds to me like its just as bad as leakage, so it might just be beating a dead horse.  Can't kill a bee for trying!

...and that is first-hand, SWIX can verify many successful dreams...

WARNING: like many clandstine procedures this is dangerous as the equipment is not stardard lab equipment but improvised instead, meaning it is not tested (unless you test it...good idea) and so take precautions and always put safety first!!!!!

Take one wine bottle, drink wine. Sober up, or, for the more adventureous, just jump str8 into the mission... Now the bottle type must be the thick-walled type wine bottles. Most are, but bee careful the odd ones are just thin glass like spirit bottles and these will shatter(!) Get some cloth-type tape. Normal vinyl/plastic tape will not work, it stretches/goes soft when bottle gets hot and slides off bottle. So tape with cloth content will withstand heat. Take couple meters ~8mm plastic tubing, coil around bottle, beginning ~4 inches above bottom. Keep coils together, wind on all the way to the top while taping on to prevent uncoiling. Cover whole coil in bit more tape to ensure it strong enough. Take another couple meters ~8mm tubing and jam one end in 1 inch piece ~13mm tubing. This then plugs into bottle (should be tight seal). 8mm tubing goes str8 up above bottle 1 meter or so then to whatever vent/system you want to do. Bottle goes in pot of oil on element. Temp is taken up *VERY SLOWLY* and never ever above a slow bubbling of rxn in bottle. 1.5 - 4 hours is usual for hypo, 4 - 8 for I/RP, depending on size of rxn quality of reagents etc.

Whoops forgot to add that water goes thru the tubing coiled around the bottle. If you hadn't figured that out already...

WARNING: NEVER EVER REACT I/P OR I/HYPO IN THE BOTTLE! VERY IMPORTANT! DO THIS IN PYREX FIRST! HEAT FROM RXN WILL SHATTER BOTTLE!!! (Learnt first-hand also... :( )

Afterwards dismantle and dispose of the bottle. SWIX used to like the fact that SWIX could walk into supermarket, spend $200 on jars dH2O matches wine paper towels etc etc and when finished whole lot goes into rubbish and no evidence (as long as rubbish carefully disposed of of course).

One last point: testing glass strength is pretty easy. Build it, put it on with just water in it and boil the water vigourously in the oil bath. If it doesn't develop cracks (or just outright shatter) you got a winner. Apart from the time I/RP was mixed and the bottom dropped out, SWIX has had 100% success.

The trouble wit getto shit you dont get the straight pooop............... a soutable size copper addapter then a suitable size cooling zakeckt will do sufice just check the safrol FAQ OK>!!!!!!!!!!!!!

Xaja:
Yes I agree quality can be an issue, primarily because one cannot distil the product so solvent clean-up only. So you gotta get good at that. Even then it still don't compare to distilled stuff - although you can get pretty close IMHO.

Although UTFSE and there will be a ghetto steam distiller in there somewhere probably that might do the damage, if you a bit of a MacGyver in the 'ole workshop....  ;)

Of course nothing compares to the proper equipment that is designed intended for the purpose, but hey, circumventing risk or just plain necessity are the realms of the clan chemist huh...
