Does anyone know what the optimal temperature of letting spice bleed into naphtha with as little as possible other fats?

1st image is naptha pulled from MHRB that had a few subtle heat baths at about 120f.

Swim started from Powdered root bark so he let this sit for 48 hours after gentle mixing and heat bath. Also gravity filtered again so no basified junk made it in.

Regardless the spice ends up looking like the 2nd picture and needs another cleaning.


I’m thinking temperature has a major effect on what spices / stuff transfers into the naphtha – there must be an optimal temp that spice goes but other stuff doesn’t so much. I mean, even after getting the spice out the naphtha remains very bright yellow. So there is something else the naphtha is grabbing.

Swim has tried a lower temperature, 86f constant for a number of days and this did pull purer spice, but not nearly enough of it. So- higher then 86 but less than 130f…. any opinions?

The DMT will migrate into the naphtha fine at room temperature. It seems heat generally pulls non-white stuff (fats?) as well, if you want whiter spice I wouldn't do 48 hour pulls. Room temperature for an hour or so is what I do, and I'll let the last one go overnight to make sure I get everything. If you feel like you aren't getting "enough" not using heat than just do more pulls.

interesting. Swim has gotten nothing in an hour at room temp. (70s f.)
Would this be using STB or A/B tech?

What exactly do you mean "has gotten nothing in an hour"?

I pull at about 110d-130d F for polar solvent temperature. Seems to be my magic zone for max yield without too much plant oils.

Any reason why you don't just do a quick recrystallization to clean further if you want it super clean?

Kash- what I mean by '"has gotten nothing in an hour"?' is that in a STB tech, my friend Swim has never been able to pull dmt into naphtha at room temp. (70's f) in only an hour. He has left some in for 2-3 days at room temp and got a little spice, but a warm bath has always been needed to pull a good amount of spice.

As far as cleaning after, Swim has had mixed results. Swim did 2 recent cleans at about 130f. Swim wishes he had been more scientific about it, in 1 clean swim got pure white stuff out. (see below) Another time, swim removed a lot of gunk, but the spice was still just as bright yellow when done as when swim started.


So it helps, but optimally, if we knew the best temp. for pulling in the first place using STB, maybe that would help keep the yellow out to start with.

I have heard some people say they do STB at room temp. That has not worked at all for swim. Swim always has to warm it up, but then lots of impurities jump in the mix.

There is this thread on the subject of the boiling point of spice:
Important Boiling Points

But that is more about boiling point and not absorption point into naptha. Absorption is not the right word though.

This other post mentions the melting point which might be close at 45c or 113f..?
boiling point of dmt, naphtha?

what is room temp at the moment?

the longer i leave the base before adding naptha, the more oils i pull through, and is increased again if heat is applied.

i leave the MHRB solution for 12-24 hours for the first 3 pulls, and then do another 1 after 48hrs to get anything left behind.

Dont mean to ask a silly question but you are mixing the naptha through 3-4 times and then waiting to separate before pulling the naptha right?

Ya I was wondering the same thing are you mixing atleast 15 mins the naptha and basic solution? Thats the only thing I can think of why you couldnt get spice at room temp in its freebase form which is quite soluble in naptha givin some good swirling/turning over.
