this isn't a new TEK as it's based on " Cyb's 50g Hybrid ATB Salt TEK " as seen in this link ! https://wiki.dmt-nexus.m...brid_ATB_%27Salt%27_Tek The only difference is this is for 100g ACRB with a step commonly known as Backsalting a mini AB or clean up at the end !

That is not a healthy colour you are right, it looks blue. What brand of solvent did you use? You can do another mini a/b and use a different solvent to pull or can recrystalize in a different solvent. I would go with the former.
Could it be from the container used?

It's cole mans naphtha for camp stoves. The odd thing is it only occurred on the one tray...where a defat was done. I'm wondering if dishwasher residue could be to blame? Otherwise not sure.. Containers were all glass or HDPE. What would be an ideal solvent instead of naphtha?

I've seen others use Coleman's without a problem , I'm stumped that this has happened to you're hard work ..

Unless they have started putting a rust inhibitor in the fuel , otherwise without know what part of the world you're in it's hard to advise you on solvents available .

I've seen others use Coleman's without a problem , I'm stumped that this has happened to you're hard work .. but not alls lost just redisolve in new solvent then proceed with another mini then repull , zippo or ronsonal lighter fluid is readily available all over the globe also

But blue is the best kind! It must be 97% purity then :O (joking of course)

When in doubt you can always use the msds. You can try redissolving with a different make if naptha. If it's not soap from the dish washer (I always clean my dishes with acetone to be sure) then it may be something soluble in the naptha itself. Plastic or dyes perhaps. So if it occurs again I would move away from naptha and use a different solvent altogether. (At least for this extraction, to be sure it's not carried over into the next re-x).

Hopefully though, recrystalizing it remove this problem for you comepletely.

Thanks, I will procure some vm&p at a local paint shop as that should be more pure. Is there a concern that whatever the "unpure" blue is will migrate over to the new naphtha? Also to note, a large amount of naphtha was evaped to get to this step..possible higher amount of impurity x.

I think it couldve been rust inhibitor or something like that.
Lesson learned know your solvent!

V and MP naptha is a commonly used solvent for extractions , the msds looks ok 100% light hydrocarbons.

vm&p naptha is legit. I use that myself. I'm glad you got that squared away Naptha does take a while, don't heat it. Instead use a larger pan like a pie dish, then dump it into something else while you precip. Just don't use something so large your evaporation is too hasty and your DMT is now stuck all over the pan

I just distilled 1.5 liters of vm&p naptha.

How was that done? And what does distilation provide for the pulls? Highshcool chemistry was a long time ago for swim.

Infid3l you're doing just fine mate , Just stick to the fan to pre-evaporate you're naps it's the simplest safest way of doing it , and you don't need to distill or clean up you're naphtha , you even said after the mini it was crystal clear .. keep up the good work ...

I don't no what ice is trying to prove talking all this unessacery lab talk with these over complicated processes .....

Uhm. Wasn't it clear? There's nothing wrong with heating naptha a little bit. I had no idea microwaving water as a safe heat source was all that complicated. :rolls eyes:

I did it using an oil bath/vacuum. I used a leibig condenser and an ice bath under 5he recieving flask. The purpose for the distillation was merely to purify and recycle my solvents.

It seems to me, (someone w no organic chemistry background) that you're way over-complicating things.

Just search the forum for "Cyb's Hybrid ATB Salt tek", and follow it step for step.

Also, even though my experience is extremely limited, I've not come across any teks that use dichloromethane. Why did you add this?

In my experience, (of extracting beautiful, white crystals on 3 occasions; 3 successful extractions from 3 attempts) vacuum filters and sep funnels are simply not needed to efficiently extract spice.

Maybe just humble yourself with regard to your chem skills and don't reinvent the wheel, ya know?

Best of luck on the next try!
