so i supose the added naptha changes the solvent proporties enough to precipitate some unwanted gunk eh?
Yes, but I can not say if the precipitate is unwanted gunk or not. With MEK, it seems that the clear layer is the more interresting.
one you just let evaporate, another you add X number of drops, while increasing the ammount until its 50/50 in your last container.
Unfortunatly SWIM have no more basic material to play with. He tried pouring until up to 75/25 naphta/MEK and it was still precipitating.
Some things SWIM learned from his experimentations :
Do not evaporate the food grade limonene, it always leaves with a oily product. It stays oily even when heated at 100+ for a while. Better try to crash out the goodies by pouring slowly some naphta in the limonene (and wait few minutes to see what happens, it is not immediate).
I am speaking about a crude extract obtained from boiled limonene that did not precipitate anything when cooling.
The dark/amber stuff resulting from the limonene+naphta can be 'dried' and is quite solid and shiny.
Acetone dissolve that dark stuff very well, so does MEK (no layer is forming at this state).
But when adding naphta to acetone, there is no milky reaction while there is with MEK+naphta. Not sure it makes any sense, I just give the info in case someone knows what to do with.
SWIM also tried to filter the dark acetone thru active charcoal (before adding naphta), which seemed to not be of any help, maybe the opposite as it may have captured some goodies considering the ridiculous amount of stuff resulting from evaporation.
So here is the next hypothetical tek SWIM will try with a small batch of seeds he may find :
Crush and toast seeds, add carbonate sodium (maybe toast again)
Boil all that in limonene for 10 mn
If something clean precipitate ... good enough.
If not, crash out the gunk with naphta
Three options are possible at this state :
MEK+naphta -> sepate->evaporate
Acetone+naphta -> sepate->evaporate
Ethanol-> slow evaporation (seems a promising possibility to crystalise bufotenine)
SWIM will not bother with A/B or re A/B of the gunk (anyway the gunk showed that is was no soluble in aciditic water)
