Vacuum and fractional distillation

[hardraade]

Holy shit. No, the oxygene will react, I think. Oxidizing\karboxylization of the C-Noids.
Its the polarity of the gas that makes it better than butane.

 

[hardraade]

The dewar must be reinforced, if its not stainless?

Now this thread takes me back.

 

[Gray Wolf]

i got a tank of liquid oxygen now, is that useable i wonder?

Oxygen also has a super critical state, but may be too strong an oxidizer to be a good choice here.

In addition to being relatively non reactive CO2 has critical points that are achievable without a lot of bother.

 

[hardraade]

oxygen will oxidize the hell out of anything organic lipids..

 

[hardraade]

Anyone with specs on how many Bar\kpa the container of co2 must hold?

 

[hardraade]

Anyone heard of PEG-cement?
Its a kind of panzer-glue thats fuckin unbelivable strong, its mixed with fibers..
If U had your glasspyrex that fitted snugly(\1 cm to spare to the walls) into a stainless container, connected all the glasstubing with those steelcouplings for gass, (make sure that all the couplings of glasstubing are inside the stainless canister, with only the steelcouplings exposed through holes.

When filled with PEG-cement (or alot of regular cement,I guess)
Wouldnt this totally seal and reinforce the system?
Making it capable of handling higher pressures?

Liquid CO2 is a solvent all by itself and doesn't have to be pressurized to work.

However liquid C02 at atmospheric pressure is called dry ice, so it would need 100 psi or so would keep it in a liquid state with the temperature stable.

It goes super critical at just under 1100 psi, so a 1500 psi system would work, which is well in the range of Schedule 160 304 stainless pipe.

neeeeveeer miiind...hehehe, I thought it could be extracted while in-stream gassing..and outlining the pressure via a pushvent\set nozzle that dont let the press.get over certain levels..
So its no other way than compl.stainless then?

Other materials will work, but 300 series stainless is probably the cheapest option, given that carbon steel embrittles and turns into a grenade at cryogenic temperatures at pressure.

If you weren't going to use super critical pressures, the system would only have to maintain a couple of hundred pounds to maintain the liquid state and other materials become more viable. Using a 3X safety factor, say 600 psi.

Ok then..dammit...these pressuresafe vessels are hard enough to come by, and in suff. volumes it becomes nearly impossible..
Its very strict here where Im at, only schools and teaching institutes can purch.those objects (It seems that they think columns and glassware in general, posess a magic force or something..odd.."everything dropped into this vessel will automaticly turn into somekind of an explosive device that with no doubt would be used to harm our nations interest")

The gov.handling of the problem is just filled with ridicule..if someone want to make something sinister, really,really bad, they dont need pyrex, for god sake..

Anyhoo..Have U tried reducing\reoxidizing the CBD\CBN back to its psychoactive form?
I mean, using hemp as rawmat. I think it can be done, just a little tricky and a lot of steps involving H2O2\rekarb.
Possible that the result have to be corresponded out as a salt, but Im not sure.
Looks like U got the equip.to give it a shot, Gray W?

We've isomerized CBD, but not CBN, to THC.

My background is engineering, but our biochemist student is already working on developing a process to turn THC back to CBD for enhanced pain meds. I will ask him about CBN to THC or CBD.

 

[hardraade]

Do u get it as a salt or as an oilbase?

Oil

 

[purple_man]

cbd -> thc IS already made by pharma corps...

well marinol/dronabinol is as far as i know: 2,5mg or 5mg thc with sesame oil as a binding/carrier. it's made of hemp, since in most euro countries it's forbidden to use cannabis as medicine, hence the pharma use hemp oil as the starting product -> makes the outcome legal (despite being thc...) sad but true...
by the way i tested em on couple occasions and well a rather happy/relaxing/slightly euphoric high they give (unless you smoke a spliff afterwards) then your in for a serious ride, especially after 2 x 5mg caps and 1-2 spliffs... (seems like intake of other cannabinoids and especially terpens XTREMLY modify the high)... and there is also a dronabinol version in liquid form (i think in suspension with alc, cant remember) seen that one only twice, and was much stronger than the pills (but i guess due to different dosages)...

sorry for the stoned ramblings! keep on the good work GF!!!

 

[Trillion]

Brilliant! Glad to have found you here Gray Wolf, still pushing boundaries(even though you Americans can't spell properly lol). You gave me a recipe for a BHO topical ointment at another site before I was banned, I'm most thankful.

I don't understand, what do you mean THC back to CBD? Are you sure the THC was CBD to start with? Hint, THC comes from CBG. At least in the plant.

[greenIrie]

I've read somewhere that isomerization from THC->CBD is possible, although I couldn't find it in any scientific literature - would you happen to have any idea Sam? I'm not a chemist but since CBD->THC is possible, could it be that difficult to go the other way?

 

[Sam_Skunkman]

You are missing my question which is, does THC come from CBD in the first place?
"turn THC back to CBD"

I know THC does not come from CBD, in the plant it comes from CBG. So does CBD.
