freeze precip or evap?

Migrated topic.
Freeze precip creates a cleaner product in my opinion. Evaporating is usually good to do after a recrystalization. If you evap instead of freezing you can be left with some plant oils and quite a yellow end product.
 
You should absolutely freeze precip your pulls, there is no reason to evap. The product is cleaner and you can reuse your solvent. As for a recrystallization, either one is fine. Freeze precip will yield a slightly cleaner product, but when you evap you get huge crystals. Its fun to do both, see which one you prefer.
 
SWIM has evapped 3 times and just recently freezed precipitated for the first time...from those extractions it has been determined that Freeze Precipitation is the definately the way to go. As already mentioned, it will obviously allow u to reuse your solvent, as well as not having to deal with nasty fumes (which of course would mean you need a well ventilated place where people aren't living and would notice). Also SWIM has learned that evapping basically takes longer than one would care not 2 wait (as where freezing for the most part takes an even 24 hours). SWIM's first two evapping tries seemed 2 yield a tan color substance with peanut butter like consistency. The third evap of SWIM was like a step backwards...it was 4 sure DMT N-oxide oil, it was set next to a window with wind blowing... (yellow colored, just like vegetable oil, but thicker, would not crystallize). The oil worked good, but was kind of a pain to work with (don't really know how much was in one drop). Now for the freeze..Another advantage of the freeze precip is U do not have to defat your solution. Another trick to get rid of that unwanted oxide (which can be caused by old MHRB that has been sitting for 2 long, is to add zinc before you basify your solution (which should be mixed for a few hours and then filtered b4 U basify)). Your freezer should be turned down 2 the coldest setting that it has 4 the precip. The freeze should be between 12 and 24 hours. From Swim's experience 24 hours is the way 2 go, 4 all crystals 2 form. You should always check along the way, 2 see how your snow globe is looking.

2nd evap (peanut butter stuff)

Freeze precipitate (This is what you want, very clean)

I hope this was helpful, bottom line SWIM will never evap again.
 
i'll do my first three pulls with naphtha. freeze precip for 12 hours or so to get as much spice to crash out as possible. drain out and reuse the solvent for the next pull. on the fourth and final pull, i'll freeze precip out as much as i can then i'll pour the remaining solvent into a big pyrex baking dish and evap it. i'll wind up with 4 pull jars filled with most white crystals and a baking dish with bigger, less pure crystals.

personally, i like the 'dirtier' stuff in my changas. i really enjoy a slightly yellow/more full-spectrum spice. the purer stuff is then recrystallized and kept separate.

then, of course, i do one final pull with boiling hot xylene which i put out in my garage for a month or so to evap into the truly mysterious JUNGLE SPICE... :shock:

L&G!!

Boiling xylene, ugh.... sure it increases the yield but... ugh, haha


But really evaporating the xylene is not only wasteful but creates a very impure product... you could simply salt it out with vinegar then evaporate the vinegar at 80-100C until it no longer smells of vinegar for PURE freebase jungle DMT....

No wasted xylene and it takes an hour or so to do, not a month. Admittedly there may be up to a small loss of final yield but it's really your choice what you'd like to do.

Just trying to give you some tips because you have given me many though you may not have realized!




As for evaporating naptha. SWIM recently did an interesting test

1:Freezer precipitate 75ml naptha. The 4th re-used pull from 200g of MHRB.
Yield: 256mg white crystal DMT
2:Salting out the un-precipitated alkaloids from the yellow naptha with vinegar
Yield: 30mg jungle DMT
3:Evaporating the still-yellow naptha
Yield: 11ml jungle DMT and a small residue of non-vinegar soluble goo that popped when under a flame.

So really there are 4 options, not just 2.

1:Freezer precipitation - pure but not ALL the product
2:Evaporation - Not as pure but ALL the product, but wastes naptha
3:Salting with vinegar - pure and ALMOST all the product but not solid
4:Evaporating then separating the DMT from non-DMT with vinegar - Pure and all the product, not solid and wastes naptha though.

The last 2 may seem a little odd and they are, but they can be made into vinegar-tinctures for easy smoking and pharma use. SWIM has been working with vinegar-tinctures for a while now and urges everyone to try making one.
SWIM recently measured, loaded and smoked some white DMT and found no difference in the experience except the effort of the process was much more than evaporating 4-8 drops of vinegar and scraping up the goo with the machine copper.


And that ends q21q21's typical overly talkative shameless promotion of his weird methods.... haha

HUGE THANKS for this little trick o' the trade! i will do it tomorrow as i was just about to do a final xylene pull....

..yeah...doing ANYTHING with xylene sucks.....that is just one nasty, caustic, stinky solvent!


NAPHTHA, on the other hand.....i actually LOVE the smell of..... :shock: is that weird?

L&G!!

Do you have a power line in your garage? I have a little magnetic computer fan mounted on a piece of polyethelene plastic wired to a 5v power adapter and placed over the dish that blows very lightly over the xylene and makes it all evaporate within a few days instead of weeks. I hate xylene smell, but outside in a shed or garage its not so bad and the resultant additional jungle spice pull after all the naptha pulls are done can be a very large yield of even more powerful and interesting journeys I've found.
