that actually sounds like a kickass solvent mixture. definitely worth a shot, seems likely that the crystals would be very clean

and yeah, one is enough with dcm. use about 1/10 volume, per basic sol'n volume.

well the boiling point of diethyl ether is 300f and heptane is 370f...or so

I think everyone knows to use shellite/naphtha hydrocarbon solvents to pull the spice initially. But lately there's a lot of interest in pulling the "jungle spice", where your solvent options are diethyl ether (hard for most people to get ahold of), DCM (reactive to DMT), xylene, and toluene. With xylene and toluene being the only commonly available choices, it'd be nice to have some more specifics on the comparative hazards (I know they're fine in well-ventilated spaces, but we're talking kitchen extractors here, not lab techs).

i definatly agree with you on that list of solvents rdwoodward. diethylether is nice it causes few emulsions and evaporates easy which is good if you dont have access to certain nice toys. it smells like shit but its not as toxic as some of the other ones.

yea im not sure what tek sais what i just said cause my friends never read them. but anyway a friend of mine once did an extraction with toluene and ether (he was trying both to see what had least emulsions etc). anyway when he collected his organic layers he dried them to find red goo (jungle spice as people here call it). and he speculated well my spice must be in this red mess. so he added warm hexane to the red mess and two layers formed. this red stuff and hexane layer. he seperated the hexane layer with pastuer pipette and dried it to find spice. nice yield too.

i guess only reason im discussing this method is that i think spice is more soluble in toluene and ether and stuff then it is in hexane hence why you can recrystallize with hexane. i think it sais something about solubility of spice in the merck index too if anyway can find a copy to take a look at. so in some ways its easier if you are safe and in good ventilated area to just pull with ether or something then purify your crude extract with small amounts of warm hexane. however i really have no idea if you get the same yield or not either way you did it.


it seems to me like the diethyl ether is for jungle spice...but since you have heptane in there as well...and im thinking that diethyl evaps faster..you may be able to condense most of the spice into the heptane(by letting the diethyl and heptane evap)..and do a freeze precip you may get some xtals

what you would probably have happen is...the pure fluffy spice would freeze precip out..but NOT the jungle spice..after you do the freeze precip..you would then evap the rest of the heptane/diethylether to get the jungle spice that didnt precip out

see you wont get ALL the diethyl out...just some of it...so the jungle spice will sit in that...and im thinking the spice will be able to freeze precip out...this is all just a guess

another thing you may try if that doesnt work is figure out a way to use an acid(im not sure what sort of acid you could use...either fumaric acid or citric acid not sure what else though..ill have to check) to drop the dmt out of the solution and then combine it with a base such as calcium hydroxide, sodium carbonate to freebase it again..and then pull with the diethyl and heptane solution...to pull out cleaner crystals

what that does is by turning the dmt into a salt..it wont be soluble in the solvent..so it will precip out..then you would pour off the solvent and let the precips dry...then mix in the base...and then add some water..stir for ten minutes or so..and you might have to let that all dry..not sure...or you could leave it wet and pull again from that



but personally..you should just smoke the jungle spice (or wait until somebody that is a bit more knowledgeable in this subject to help you figure it out)its awesome...SWIM has had amazing journeys from it

yes that would be much better...

you should dissolve the jungle spice in the heptane using some heat...there will be a yellow puddle at the bottom..be sure not to pour that off when you pour off the heptane..then evap the heptane down a bit till you see crystals starting to form...and then throw that in the freezer for instant snow..once that is done..pour off the heptane..and evap the rest for anything that may still be in there...or use it to pull from that yellow puddle you have

because there is still more spice left in the yellow..do it until it becomes really dark

Just so you are all aware spice is soluble in diethyl ether no problem. It would not work well for recrystallizing unless you evaporated off most of the ether. heptane on the other hand is excellent for recrystallizing.

be careful ether is very explosive but when used with care is a fine solvent. it does extract the jungle stuff too though.

^^if SWIY carefully controls the temperature.
