Hello all,

long time lurker, decided to signup today - hello everyone.

SWIM needs help with extraction.

SWIM used 600ml water, 100G lye, 100G mhrb

followed steps correctly and used HEP Bestine to pull

(it worked)


For second extraction SWIM used xylene to pull because SWIM ran out of HEP Bestine

(it did not work)

SWIM left in freezer to precip all night and it is still just jars of
xylene... no crystals to be found ...

any advice on what to do with this or next step in the path of SWIMS crystal voyage.

Hi there,

I'd recommend doing some more reading on the forum to learn about the different properties of non-polar solvents and how DMT behaves in them. What you need to search for is "mini A/B" or "backsalting" because DMT doesn't crash out of xylene (and other certain solvents) at freezing temps.

Freeze precipitate xylene/toluene/limonene ?

Also, no need to swim, the water here is only knee-deep!

Good luck

What the greatful one said you will most likely need to back salt with xylene or you can evaporate it as well if you aren't concerned about reclaiming your solvent

This is what I was searching for but wasn’t running into any lucky on how to do this operation- I read the above already and have been researching around.

Didn’t want to tell SWIM to evap as I have read many saying it leaves yellow oil gunk

The end of an A/B extraction will work in this case. HCL is probably best for this situation. Check out Kash's A/B tech. The final step using HCL to pull freebase out or xylene.

swim added 100ml water to all the xylene pulled and .5 ml hcl twice over 10-15 mins.

layers separated and siphoned separate into beakers. will let them evaporate over night and see what is next

will crystals that may be present and scraped need rewashed in naptha or acetone

since they were in hcl?

The HCl salt of dmt will not crystallize nicely from watery solutions. Like the acetate salt, it is too hygroscopic.

ugh. what’s is your advice now? thanks

so the hcl water has been sitting a few days now and hasn’t evap much all


any suggestions for SWIM to speed this up or process it differently?

Read FAQ. Read Attitude.

Read Entropymancer's excellent extraction overview. (linked in the FAQ btw.)

Then: Base aqueous layer. Extract with naphtha. Separate naphtha. Freeze naphtha.

Don't hesitate to ask questions that are not in the FAQ or that are exceedingly hard to find with even the most persevering use of the forum search page. In all other cases, try to do your homework and study the relevant basics (you did read the Attitude page, didn't you?)

you can remove the water below the layer with syringe(not the best option? dont know) or move it to a wider dish for faster evap
