Dry ice for freeze precip and recrystal

dimethyltryper · 06-07-09, 02:52

someone i bumped into earlier today was asking me a question and i figured this was the best place to ask.

my friend wanted to know if a scientist would be able to use dry ice in a cooler to conduct a freeze precip experiment and then do a recrystalization? would this scientist have any problems w/ gasses mixing form the dry ice and np solvents? what would happen if the scientist was to get the supsension too cold? the base would just fall correct? how cold is too cold? The scientist wants to take jar and put in cooler with 8 lbs of dry ice for 24 hours. would the scientists plan work?

I've been curious about this.
I don't see why it wouldn't work.

Let us know how it turns out

there really is no "too cold" as long as the solvent itself does not freeze.

Dry ice is neg 108 degrees F. Naphtha freezes at neg 22. With 8 lbs I would imagine it has the potential to bring the jar to negative 30 degree temperatures in farenheit.

But, if I put a thermometer in there that can be accurate at sub freezing temperatures and bring in warm air I may be able to hold it at a negative 20 degree temp for several hours which may be benifitial. But I am not using naphtha for the second crystalization. Hmmm.. I will figure this out. How long does it take for the freeze precip to complete? I've never done one and cannot get a decent answer anywhere.

SWIM usually gets nearly all the DMT precipitated overnight in a freezer that gets to 0 degrees, but it may take longer depending on how cold the freezer gets. !2-24 hours should be plenty for most freezers..

dimethyltryper · 06-07-09, 18:23

So,

How is this story I just made up?

"A scientist put his jar of cheddar cheese looking dmt in a towl being wrapped by two heat pads on high. His hands got burnt 10 minutes later and the dmt looked like movie theater popcorn grease. The scientist put a tiny bit of naphtha in the jar and swirled until all cloudy. The scientist put it in the freezer."

I now don't know how to finish the story...

Should the scientist leave his .4 grams in the freezer for a few hours, then take out, let go to room temp, swirl, place back in freezer. Do this for the rest of the day. Will the gunk be condenced to the bottom of the jar for easy removal? The scientist just wants better dmt, does not have to be even white at all, he just wants it to not be gooy.

Because there is so little dmt in the jar, could the scientist add some freeze temp naphtha before he breaks crystals off, so less is left behind on this poor?

D-Tryp

Oh yeah, next time scientist will heat naphtha to add to dmt. I wanted that in my story so the readers will know he's a newb. But i doubt it did any harm what so ever.

lysergic · 06-07-09, 19:34

You melted the dmt before you added the naphtha?
If you did, depending on how hot you got it,
you might have oxidized or even destroyed the spice

Hope it's still ok,
Next time you should definitely just dissolve the crystals in warm naphtha.

dimethyltryper · 06-07-09, 19:57

Gosh, well. No one ever did anything, actually. But the scientist in the story did

, yeah. I should note that in this story the scientist just discoverd more crystals in some dishes from a while ago. But the scientist in the story has crystals growing already from the over-heated dmt. If it means anything or not, the scientist is learning.

When I'm going for ease, opposed to big crystals or the such, I just dissolve in hot solvent, put in a glass in the freezer over night, and in the morning there should be crystals grown around the edge of the glass and along the bottom. Just tip the solvent out, scrape the crystals out and dry them.

Hippie3 · 06-07-09, 23:14

wrapping the dry ice
in several layers of newspaper
slows its' evaporation
and should
give you more control
over how cold the chamber gets.
dial it in using varying thickness and quantities of ice
until it's where you want it...

As long as it didn't vaporize, it's probably okay. Just get some solvent hot and redissolve the DMT in it. One can then let it cool. If some orange/yellow begins to settle out in a separate layer, the white solvent on top can be decanted into a fresh dish to evaporate or be frozen to freeze precipitate. This should come out white, while the yellow stuff will crystallize, or the procedure can be repeated until one has gotten nearly all the DMT from the yellow/orange goo.

Yeah, no matter what just happened, I just wrotre more of the story:

"The scientist loaded a bowl of some nice white crystals that he just recreystalized, about .3 and it got him pretty good for about 10 minutes. Ha has been smoking about .5, he's been getting better w/ the weed. What he does is put a tiny bit in the bowl, smoke it and get the bottom kinda clogged. Not too much. Then he put a thin layer of weed over that ash, Then he put the layer of deemster down, then he cover the entire top complety with weed... He lets the flame just hit the weed on top then moved it until all of the top layer is smouldering. The he holds the spicy hit and his face is dumb by the time he exhales....

He is very happy with the re-crystalization. He is going to do it again w/ the 4th pull (just done today). The scientist sees a ton of cloudiness in that last pull. Freeze precipitating the pull now, will strain tomorrow, and do a second recrystalization on the first pull, and combine it with the presumably nasty 4th pull (it's been sitting for about 4-5 days). Hopefully the scientist will have a nice white-tan colored amount tomorrow. He is also getting some n-heptane and will probably do a final third/fourth to get some super clean glass/whites. Scientists wants to get all the experimenting out of the way...

The scientist put .37 in the jar, scientist now has whiteish crystals.47!!!??? WTF?!?!!! Scientist also removed a huge gob of some pretty nice crystals but forming in pools of orange gunk. Had to weigh .3 on it's own. I dunno what's up with the scientists scale. But it's making me nervous

Tune in tomorrow to see what the scientist in this story does next.

How is a scientist to seperate goo from dmt? The scientist in this story uses a 5 x 7 (in) pyrex dish. I think there is just little around his house that is narrow enough to work. ANy ideas?

Maybe once the scientist sees yellow forming he will add warm naphtha and run over the top to collect the saturated solvent. He will undoubtingly lose some crystal, but he can then proceed to freeze precip. #4, and do this until he no longer can form a white crystal.

He should look for a candle holder maybe?

this is certainly the way to do it. if i am there to see this experiment take place, i will certainly mention to figure all this shit out before there are jars in the cooler. ha ha.

SWIM normally does the recrystallization in a jar, then pours the white solvent off the top of the yellow or orange solvent that separates to the bottom, into a baking dish to evaporate, then repeats the process on the orange stuff to pull out more DMT. How many times it is done is left to the scientist's discretion.

dimethyltryper · 06-08-09, 12:48

Cool, I will note that in the story. The scientist also got .4 more out of his last mhrb extraction, making the total from 100 grams 1.85!
