Accidentally used KOH instead of CaOH2

I was intending to go with the hielo route but I messed up and used potassium hydroxide instead of calcium hydroxide.
Is there any way I could still get something out of this? Is A/B possible with KOH like it is with NaOH?

Rn I have this paste I'm thinking I could add some water extract it with naptha and then take the freebase dmt put that in ehtyl acetate and salt it that way?

KOH and NaOH is almost interchangable from what I've read... but you can't use it with ethyl acetate since it'll breakdown to alcohol

The path you choose sounds right... Pull with naptha and freeze precipitate then you can salt the freebase with ethyl acetate or directly by using appropriate amount of acid since you can calculate based on freebase you have.

Oof, thanks for the relief. Got scared thinking I lost 100g of mhrb
 
One more thing I'd like to ask. Is there any tek you'd recommend? The only one I've done before is A/B but considering this one is already mixed it's gonna have to be stb.

The normal tek of pulling with heptane/naptha and freezing would work well... IDK tek names.. I think Cydx ion tek? I always add salt to my extraction sit helps prevent lots of headaches and improves extractions a bit.

Add water to your bark and KOH add salt as well. Then add naptha in appropriate volume less is more but you can always fix later if you used too much. Separate and freeze overnight at 20C. And decant off and save naptha for next time.

You can then do mini a/b if you don't like the quality before salting. Adding an acid to your naptha and pulling with a fraction of the used amount helps recover a small amount that is soluble. (important step if you used too much)

Lots of teks idk names but Pretty sure it is ion tek... think Cyx or something

EDIT:
Cyb ION tek ... it is a a/b but you can just do the base step with salt added.
 
The main concern would have been the strong reaction when adding it initially to the bark/water mixture, you have a basic paste now and are good to go.

1. DO NOT ADD ANY MORE WATER! (to avoid said strong reaction)
2. Just submerge your basic paste/dough in fresh naphtha and stir gently to extract into the solvent, do this 3x and combine all 3 pulls
3. Evap halfway and throw in the freezer for 24 hours
4. Collect your product.

:cool:
 
Ok, I was thinking there might be some problem with exothermic reactions. Won't the paste extract less though?
I'm thinking it might be possible adding the paste slowly into water not the other way around but your way seems easier. How much do you think this could affect yield?

Mini question: charcoal fluid can be used instead of Zippo lighter fluid as long as it evaporates clean right?

It shouldn't effect yield, as a stronger base it should be even a little more effective than lime. You don't want to stir too much, just carefully stir the solvent into the dough (it usually takes on a bit of a crumbly texture with a lime based dough). There will often be a pretty noticeable color change as the alkaloids transfer into the solvent.

Yep, as long as the evap is clean it should be good to go. (y)
 
Thanks for the help.
I think I'll like the paste extraction more than the classic liquid one. It was annoying trying to get as much naptha in the syringe without getting base solution as well. Will get to it tomorrow.

Do you know of an extraction using this sort of method before? I wonder how it'll mix since naptha is fully non polar and ethyl acetate is at least somewhat polar.

You can clean up stray droplets of base soup in the pulls by squirting into a jug with a little water at the bottom. Ideally, this would be distilled water with a little sodium carbonate dissolved in it.

Collecting the last bit of naphtha gets easier with the use of an inverted funnel to gather the thin layer into a more perceptible depth in the neck of the funnel. You only really need to do this on the very last pull, since remnants from preceding pulls get recovered in the subsequent ones.

You may as well dilute down your KOH bark paste at this point, to make it easier to stir in the naphtha. Take care - it might get rather hot.

If you decide to stick with the paste, a fork will help a lot with the mixing.
 
Ok so I did the extraction but the paste kept absorbing the naptha. It became more difficult by time and by the end it had tripled in volume. Is there any way to split the naptha from the paste? It's very liquid now so it's hard to extract more.

yeah it's called a drytek, here's one Microwave Assisted Drytek (MAD Tek)

when I tried doing MAD Tek I ran into the same issue and I think the problem was that I used NaOH instead of CaOH, so for you it's maybe bcz you used KOH, maybe only CaOH is suitable for dryteks but I don't know why. Adding water will solve this by replacing the absorbed naphtha and forcing it to the top, but now the exothermic reaction is even more undesirable with all the naphtha in the mix. when I did it many years ago I didn't really think about the reaction and it went fine, I do not remember well how it was but it probably got super hot. how much KOH did you use and which is more reactive NaOH or KOH? perhaps you can do it safely with a proper glass vessel, placed in a bucket, in a well ventilated area, and taking all safety precautions. I don't have chemistry background so please consider the opinion of more knowledgeable people.
 
Ok so I got another question. How would one pull the DMT out of a solvent that doesn't work with freeze precipitation. The charcoal fluid just got milky in the freezer but no crystals forming. Is there any way I could get the DMT out of that and into a lighter naptha say Zippo fluid?
I'm thinking of just evaporating it

Evap is a good route. You could also mix with acidic water and roll the layers through each other, this will pull it into the water layer. You'd do this 3x with fresh acidic water. Then combine and base the water and pull into your zippo fluid, again 3x with fresh solvent. This is a backsalt and can help clean things up, but it's a lot more work than just throwing it under a fan near directed out an open window and evapping.
 
Ok another update, the naptha is taking really long to evaporate. I guess charcoal fluid wasn't the best choice, anyways I'm thinking of just mixing the naptha straight into the ethyl acetate and salting from there. Is there anything wrong with this route?

I think as others pointed out you need to skip the EA part, it will only complicate things at this point. you can back salt into a minimal amount of water and vinegar and then proceed from there. you can pull with a better solvent or a smaller amount that will evap faster. I don't know about the EA approach but maybe after backsalting you can drive off the water, mix with CaOH and pull with EA.
 
What sort of acid would you recommend for back salting, will vinegar do? Also how much water do you think is a safe amount, I'm thinking maybe half the volume of my solvent.
