Good day all.

I've been doing boils of my bark for a while now and was toying with the idea of using a pressure cooker. I think that it might break down the chemical structure even more for a better yield. I am concerned that the extra heat may cause some damage however. I'm no scientist so if someone could tell me if this is good idea or not, that would be fantastic....

PC is what I'm doing as of late, seems okay so far.
I love to let the pressure come up and then cook for like 30 - 45 mins, and then heat off/let cool down just until pressure drops away (no need for the pot to cool down completely for this), then warm/press up again, etc etc, like waves of pressure and back.
The hypothesis is that the pressure gets the water deep in the wood, and the de-pressures takes the goodie material out the bark. Dunno if that really benefits like that, but it's just taking the chances for it.

you don't want breakdown (decomposition) of the active alkaloids, the pc doesn't do that anyway. what it does is physically lyse the plant cells.

To expand on this, water boils at 100C; DMT boils right about 340C.

indeed.
at a pressure of 15psi in a typical pc, water boils at ~121C...still well below the b.p. of DMT.

To expand on this, water boils at 100C; DMT boils right about 340C.

I guess 340°C is for DMT in salt form, isn't it ?

340C for DMT freebase at 1atm or 760torr.

May i ask you a source for this cause i don't find anything but wikipedia and i don't trust it 100% ? Thanks

So that's a resolution being yes then. Thanks guys

I couldn't get that site to load, I tried uploading a german paper but it was 15.5mb -.-

I did a lot of test runs using a pressure cooker without jars, if you search you will see.

I found that I was able to turn the extraction water really clear in about 3 cooks at 13-20psi (30 minds each). While normaly it takes me 6 cooks before the water becomes more clear.

The pros are definately there is no acid stench in your house as you take the pot outside to vent all the steam off. Also, less time for each cook 15-30 minutes.

The cons are that the acid can stain the stainless steel pot, but you can use bleach on it after and it does wonders. Also that sometimes the bark can rise the the surface and block the vent whole and it can be hard to know when it is at the right psi without a guage and you can risk overpressuring the cooker and maybe go BOOOM! Also con is the size of pressure cooker over a giant crock pot.

Only use stainless steel! Aluminium will create some toxic oxide I think.

I always converted DMT to its citrate salt, --odors-were not an issue.
