Fresh Frozen vs Bone Dry - Thoughts???

Of course, that is the thing about N-butane. Easy to make a liquid or a gas, With a slight bit of temperature control and using only gravity it can be poured and then purged with no pressure un-like propane.

Oh, BTW, ethanol is only my transport and cold filter solvent. I have a closed loop set up I am getting going in another thread.

Though I have wonder at just using ethanol in closed loop.

Have you read much about that in the literature?

Haven't read anything of the like, haha.
It's an interesting idea but I think it would be better accomplished in a pressure vessel or something like that, I think closed loop systems that are designed like your littlefoot are more or less meant for a solvent that can be both evaporated off very easily but can also stay in contact with the material for long periods of time, and alcohol is most certainly not something I would use for a long soak, but who knows I don't even have a closed loop so I haven't done too much homework on the subject
I'm thinking if I extract with tri-chloro-methane and distill it off for reuse, I can remove the residual chloroform by diluting the extract in ethanol and distilling under reduced pressure.
And I'll be wearing the appropriate gear when I perform the synth and the extraction so I won't be worried about breathing the actual vapors, but since one of the byproducts of combustion is hydrochloric acid, I know I'm going have to do something like dilute the extract in ethanol and distill off and recapture it in my distillation setup a few times, using fresh ethanol each time, to try to fully remove all residual chloroform from the extract.
I guess we'll see how it turns out, I'll be posting the process after I figure the least wasteful way of using this stuff.

Ah, a reflux still? Slow concentration, of the target over time, most of the liquid returns down the column?

I see you have a quote from Leibig. This is an interesting condenser I found.

Should we? Fooling around? See what happens?

I'm challenging your attitude with this, in joking way.

More seriously, the more people fool around, the more people get hurt. The more people get hurt, the more the Elected of us, take notice.

Already in CA, they are trying to set up extraction as a Drug Lab Scourge.

They call shatter, pot crack. OK?

So, chemistry is serious. You can go boom, etc. OK?

I learned my lesson in 11 grade High School. Sugar and Potassium Permanganate in the lab. It was in a pour lip mortar bowl. I lit it with the bunson burner. Woosh!!!

4 ft flame, pretty! Ohh.. Then my buddy..(we had sneaked in to do this) slapped down the asbestos card on top. wooooooooooooooooooosh.!!!! (OMG!!!) Rocket flame from the pour lip.

The pour lip was pointed at me....almost. That, now 5 ft flame, shot right past my good stuff, at waist level and singed my shirt.

We were stupid. Don't be stupid, out there, me included.

lol. I worked in a laboratory for 5 years.. working with so many solvents.. I know my stuff lol... I wont do anything im not comfortable working with..

but I wouldn't recommend anyone fooling around with solvents.. I just ment I can try to clean up extracts or I can extract with it .. experiment a little..

OK. It really needs subject matter expertise. No one can be too careful, so I'm glad you took that in the spirit intended.

The prosecutor's worm turned in CA, based on 2 guys in a motel room.

They blew it up and one guy blew his legs off, as well.

Everyone can be more careful than that.

And to the prosecutors it just looks like another "shake and bake" meth lab, gone BOOM.

Boom is boom.
