Sorry, SWIM finally read this thread, and these didn't seem to have been addressed.

no.
Quote:Wash mimosa with acetone. Discard acetone.
Make a 1:1 mix with mimosa:sodium carbonate (even 5 parts mimosa to 1 part sodim carbonate should be fine)
Make it wet to a thin paste-like consistency.
Let it dry completely OR mix with anhydrous magnesium sulfate (= drying agent)
Extract DMT-freebase with acetone
Evaporate acetone
? that is what I wrote almost word for word?
The difference in crakkbakk's and Infundibulum's wording of the method is firstly that the ph wouldn't be measured, because a paste is being made, not a solution. Secondly, that the magnesium sulfate should not be hot when it is dumped in; rather, it should be made anhydrous by evaporating the water contained in epsom salt via heat. Perhaps crakkbakk understood this but did not express it in such a way.

The acetone for the carbonate extraction - does it have to be anhydrous or is that just for FASA type extractions?
I'm not completely sure of this method, but this is what i see.

2) Dry completly?, thats one thing i don't understand, if your going to use acetone to extract the dmt why do you have to make sure its all evaped before continueing?? If you evape the acetone left in the mix after washing(AFTER washing and discarding until oils are gone) anything left in the acetone will be left behind in the powder being that oils dont evaporate. so why make sure its dry, why not just press on and add some water and sodium carbonate?

The drying is not important after defatting, but by using anhydrous magnesium sulfate as a drying agent in the basified paste, the acetone you use to extract should turn out quite incredibly anhydrous by the time it's decanted.
The problem with not drying thoroughly is that there will likely be a good amount of water contamination, which isn't likely to hurt the process that much, unless you're using FASA methods. However, even if you're not, it takes much longer to evap for freebase retrieval if there is water contamination. There will almost always be some water in your acetone during any phase of this, so if you do your best to reduce it by drying between steps, the contamination should be minor and negligible.

The thread originally asked if sodium carbonate would work. This question was answered by saying no not in naphtha but in DCM/chloroform or acetone. The acetone sparked interest and the thread shifted to acetone related questions where questions where answered in that you need to acetone wash, base with sodium carbonate, dry, extract with acetone, evaporate. Now the thread is just on logistics.
Yes, so there's no need for everyone to be arguing about which teks are easier/superior/more efficient. Each tek will live or die by its own merits. Sodium bicarbonate does not work very well but can be made into sodium carbonate which works very well in the newer acetone teks, but not so well in standard STB or A/B.
This is why SWIM prefers to simply link back to previous threads regarding this, but it can be difficult for SWIY's to have to review an entire thread. The ultimate solution is to develop a tek or perhaps a handbook that discusses all the teks and the options involved with each tek.
