Drying acidified water to base with sodium carbonate to extract with acetone..

Migrated topic.

I decided to not post in my other thread in A/B because it is getting to long and too many different topics.

Towards the end of that thread, we were talking about washing with acetone, making a pastey sodium carbonate solution, basing the rootbark, then drying out the water with magnesium sulfate or evaporations because water and acetone are miscible.

So, lets say I started off an acid base with citric acid and water, added it to root bark, seperated water + citric acid + alkaloids, based it with sodium carbonate, dryed it with magnesium sulphate, extracted it with acetone.

Does this sound good? Any theories on why it may not work, any thing to make it work?
 
Man you ask too many questions!:d

Why don't you have a go the standard way (e.g. A/B or STB), pull with naphtha (freeze-precip and the rest) and get some product to try?

Then you decide if it is worth extracting more, and/or if it is worth pursuing alternative less-tried-by-everybody methods!

Right?

(BTW, what you proposed above is pretty sound, if you are not afraid of decomposing the alkaloids during the boiling off step of the acidic extract)
 
I probally ask too many questions, but it is going to be worth it when I write up a huge extraction report. I believe heavily in the giving vr. taking theory. I don't mind writing a super report even if I end up disliking dmt. I would be giving helpful info to people who could benefit from it. I want to be a research type person when I am older, doing complex papers on comparing different methods of things.

My goal is to take rootbark from the same batch and doing three different extraction on it to give an excelent comparison guide. I just got 90% of my supplies today :).

Edit - I dont want to boil it away, I want to dry it out by magnesium sulphate.
 
That's going to take a rediculously large amount of magnesium sulfate, unless you simmer the water down to a reasonably small volume first. With the carbonate/acetone STB process, you only use enough water to make a thin paste. With A/B extractions, you end up with a couple pints of liquid (depending of course on exactly how much rootbark you're processing)
 
indeed

the purpose of magnesium sulfate is to 'dry' your nonpolar solvent containing the alkaloids in freebase form, which might have some water in it, and decant the solvent to another container.

(the way to do it): perform normal a/b, extract with nonpolar solvent, pour solvent over a small amount of epson salts, and pour the solvent into a dish for evap or put in a container for freeze precip.

That is a good point haha! Thank you.

Could this be done with excess sodium carbonate added to water/dmt acetate to freebase the dmt and form sodium carbonate monohydrate while quickly adding acetone?
Or could you add excess sod.carb with acetone and then freeze it leaving the dmt dissolved in the acetone ready to be poured off?
 
The route you have described should work fine. Sure, evaporating a couple pints of aqueous solution will take some time. But it's certainly not impossible. Keeping it on low heat for several hours until it has evaporated would not be too difficult.

When you mention the initial wash with acetone, is this to remove some of the other acetone-soluble components of the bark? As far as other alkaloids, namely NMT, I don't think they would be washed out until after you basify, so they would still be in your final product. That's my understanding, at least.
