I can't believe that it took nearly two years from the time this thread was originally posted, before Swim finally decided to try out this gassing method.
It produces quite a bit of gas with very little work involved.
As per Geez' recommendations, Swim used an empty 32 oz IPA bottle, a #3 rubber stopper, drilled a hole in the stopper with a 1/4" drill bit to accommodate a 2 foot section of aquarium tubing.
Swim accidently poured in too much muriatic acid.
When he discovered that it wasn't producing any gas, he just decanted the excess acid from the damprid for later use. Connected the stopper w/ tubing, gave it a quick shake and off it went.
When gas production decreased, all it took was to add a little more acid.
After awhile, crystals will start to form on the tubing.
This works awesome as a follow-up to the "tetra trap"; resulting in gakkless pseudo.
Swim would guess that one can easily gas 6- 1 quart mason jars, containing 750ml of NP solvent in under 10 minutes.
When finished, one can remove the stopper and put the original IPA lid back on in anticipation of future projects.
Specific gakks travel with water. As I'm sure bees that prefer to titrate, realize by now. No water = No gakk!
Swim used xylene as the NP solvent and dried with baked MgSO4 prior to gassing, although not certain if it was entirely necessary. The GUPS tend to absorb alot of water in the tetra trap.
Swim can also attest to improved yields over titration. Wareami mentioned it before, but Swim can definately see a correlation between heat, evaporation and smaller yield percentages.
With this gassing method, I'm sure one can theoretically pick up a few gs both before and after the rxn.
Recrystallization takes care of the rest.
Much thanks to Geez and VE...
Edit: Coincidently, someone had to start a new thread on the same subject.
