I am reconverting and every time i pull I get about 200mg from about 50ml of naphtha each time. I am probably up to pull 15. I keep freeze precip but the crystals just keep on coming. Pulling at room temp. Argghh will this ever end? I am think I should just fan dry all of this an dry tek it.. The real problem is, if my naphtha is doing this with a rather clear fumarate reconversion then how much DMT would be stuck in the standard extraction jars?

How much material did you start with? Which tek are you following? If this is a wet tek, and you are not doing so already, you should be able to add salt to improve the partition into the solvent ( CYBs Max ion tek)

So you know the upper bounds of the yield.

I've done many extractions so i dont follow teks anymore but something similar to lextek i guess. It is just my naphtha never did this before, maybe they changed the properties of it to avoid dmt extractors getting the goods?

So you know the upper bounds of the yield. Yeah 1% from the acacia analysis threads. But that proves to me with certainty that something is up when it takes me over 15 pulls to reach 0.7%

So this coincides with a new naphtha bottle? Also, are you sure you basified enough?

Also, are you sure you basified enough? yeah absolutely. there is a lot of lye in there! I am gonna try adding salt and mix for longer and see if that helps thanks

I"ve had something this experience before when converting from fumarate to freebase and doing various extractions. It seems like you can never get all of the DMT out of the aqueous layer, e.g. you only get ~80% on each pull, so it's 0.2*0.2*0.2*0.2…= 0.2^N remaining in aqueous layer for the Nth pull. I was never able to recover 100% of the DMT using this method, there would always be a layer of fluffy white DMT floating the top of the aqueous layer. Xylene seems to get more, but then you can't freeze precipitate… For this reason I now use sodium carbonate+acetone instead to do fumarate->freebase conversion, which seems to have less losses.

I am having a similar experience. per 100g mhrb basis I am using 100ML 5% vinegar mix for 20 minutes 120ML hot water mix for another 10 95gram pickling lime. I then use naptha as you, warmed up solvent, with the plate of bark over boiling water and mixed for 10 minutes before filtered into a jar and then poured onto a glass plate and freeze precipitated. I have done 7 pulls totaling 3.3G of this same bark in a week and a half. I have done evap test on my solvent evaporates clean. the final product is 100% dry white powder crystals, no discoloration or anything. I usually only get 1.5-2g off 100g, only thing I changed was the amount of lime I used, 95G opposed to 60g Learning is the paramount delectation, and tribulation in life. ~Astonish

Quote:I am having a similar experience. per 100g mhrb basis I am using 100ML 5% vinegar mix for 20 minutes 120ML hot water mix for another 10 95gram pickling lime. You add 100 ml vinegar to 120 ml water and soak for 30 min? That's a very low pH and short soak time. Maybe to short to dissolve dmt into solution, like doing STB tek without waiting long enough. And if pH is too low, maybe lye can't reach high enough pH? Try adding 60 ml vinegar to 300 ml water and soak for 2 hours @ 60 C prior basing.
