If you have purchased VMP recently, shake it up with water and a small amount of acid. You will notice that the water becomes cloudy and will not clarify. This did not used to be the case. The two layers used to separate completely and stay crystal clear. Something in the mix is becoming slightly hydrophilic when mixed with acid. What ever it is will ruin your final outcome. Some states have the same ingredients and others have changed for some unknown reason. The only way to know for sure is to test it.

did you check their websites for any possible updates to the MSDS's ?

No and I wouldn't take their word for it anyways. I'm thinking its some kind of drying agent. It will cause the DMT to burn your lips and throat. I just don't want anyone on here to hurt themselves.

Have you actually had this happen yet? I have heard it a few times already & I have been meaning to go find a can of naphtha that does this to see if there is a simple solution.

All you have to do it put 50 ml of 5% distilled white vinegar and 50 ml of naphtha in a bottle. shake it for 60 sec and poor it into a jar or something that you can see through. You will see the naphtha separate from the vinegar. If the vinegar is cloudy and will not clear up within a couple of min then its no good.

I just did a test on some klean strip VM&P Naphtha that I purchased online MFG date - 12/03/15 and it's no good. The naphtha that I just picked up from a nearby store MFG- 1/26/16 is good and passed the test. So some of you definitely have bad naphtha. Test it!

1.Combine equal parts of the suspect naphtha with a strong solution of NaOH. Mix well and allow to separate. Discard NaOH.

2.Combine equal parts of the suspect naphtha with a strong acid solution. Mix well and allow to separate. Discard acid.

3.You now have (clean) naphtha.

That could def help, but only in the case the impurity is polar. If it's non polar, that washing won't clean it. Do we know for a fact what impurities are there?

Otherwise definitely do an evap test after washing it to see if it leaves any residue even after washing.

And maybe also it would be worth to consider other alternative extractions that use other safer solvents.

Good point endlessness, we simply don't know what the new additives are, so there is no way to be certain that a certain procedure will clean up and purify the naphtha sufficiently for use in extractions.

I would like to make a conjecture about the possible nature of the new additives. In my part of the world, I've seen butanol and butoxyethanol added to thinner and solvent formulations, sometimes even completely replacing naphtha. Both compounds are somewhat polar and partly dissolve in polar liquids, such as water and acidic water. This would explain the clouding observed, if my conjecture is correct.

So if this is the case and if only moderate amounts of partly polar additives are present, repeated washings with water will make the solvent useful again. If it consists entirely of partly polar solvent, then aqueous washings are of no use.

It would be useful if somebody could distill an older batch and a newer batch of this brand of solvent and take note of the boiling points observed at the top of a column. Contacting the manufacturer and inquiring about the changed composition might even give a direct answer.

Can you clean your DMT after using the bad naphtha? I'm afraid to use some of my dmt. A re-x wont work so what should I do?

Why won't a re-x work? I'll confess to being a little baffled by what appears to be an unstated assumption.

Obviously, using the same naphtha wouldn't help but surely you'll be wanting to get new solvent anyhow?

And then there's the mini A/B, which also would require clean NPS.

because naphtha can absorb the chemical just like DMT. Its not going to fall to the bottom of your glass with a re-x. I think I'm going to turn the Freebase into a salt and deal with it that way.

By your logic a re-x wouldn't ever work, for anything. Which clearly isn't the case.



(The solvent is not evaporated for a re-x...)

if I use clean naphtha for a re-x trace amounts could still be there. I understand what you're saying but for me its not worth it.

Just performed the test on the latest Klean Strip I bought a few weeks ago. It would appear that the vinegar stays in the bottom of the jar crystal clear, while the naphtha rises above it looking a little clouded. The vinegar should be the bottom layer correct? and I would be in the clear then? just making sure I don't injure myself

No guarantees, but it sounds okay. Always do an evaporation test on a small amount of the solvent before using it.

There are several ways you can clean DMT from different possible impurities, for example:

1- Recrystallization
2- Mini-A/B
3- Precipitating the fumarate with FASI/FASA, washing with cold acetone or IPA and reconverting back to freebase


You could do any of the above or a mix of them it all depends on how thorough you want to clean and what the suspected impurity is. Of course the best is to just use clean materials to begin with and not have to clean it up later.

Bad Naphtha.......
This picture was taken after a 2nd acid test on the same naphtha. It appears that a simple acid wash doesn't clean it very well. Sorry about the picture being sideways.

You're right not to trust them. I rarely see a genuine composition in an MSDS for naphtha, they use vague terms and often don't mention additives.
