Crown and Klean strip VMP have changed chemically.

normally, when I did injections, I used to see PEG (polyethylene glycol), which has a characteristic polymeric pattern as well, but the difference is 44 between the peaks. that was not seen in this run.

Those are much larger molecules than I was expecting to see. Some waxes might be that heavy, but definitely wouldn't evaporate.
What would be that heavy, but still evaporate at STP? My best guess would be a halogenated terpene.

I'm still baffled by how it was derived from acetic acid in naphtha. it had difficult solubility in ACN/H2O.
I'm thinking naphthenic acid derivatives. if it was purely a nonpolar compound, the detector wouldn't have given a signal.

I guess it's time to find a different solvent. The naphtha could be acid washed until no precipitates form in the acid, but at that point, I might as well just acquire something like hexane.

Hold up... I'm literally days away from my 1st extraction with klean strip just purchased a couple wks ago, and after dozens upon dozens of hours of research this is the 1st time hearing this?!
Does this affect stb, bcuz I know I've shared what tek I'm doing - along with the chemicals I'm doing it with - and I've literally gotten the green light everytime. What gives??? :surprised

Just test it. I teach you how and it's very simple.

Ok. Water, naphtha and what for acid (if it's a stupid question, I apologize.)? I saw some1 recommend 5% white vinegar, I only have apple cider in-house...
I appreciate the info. Apologies for ressurecting this thread.

Pick up some vinegar. It's cheap and easy 2 find.

Ok great. 5% White vinegar, mix mason jar 8oz with water and naphtha, add small amount vinegar, say 50ml, shake. Water is on bottom, if cloudy, bad. If naphtha and water layer are clear, proceed with extraction?
Thx again; take care.

No lol. 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.

^ Sorry for the orientation. This is after appx 3mins. Still looks cloudy. No good, correct?

Well, the naphtha separates clear. Can't you just decant it off and try shaking it again with vinegar. If vinegar runs clear, then you've succeeded in cleaning up the naphtha.
Something must be washing into the vinegar to cause that cloudiness. Has anyone tried repeated vinegar washes to clean this stuff up? Come to think of it, perhaps Syberdelic did ^^up ^^there ^^somewhere - or maybe not.

I mean I could try it, but according to the nexus, consesus seems to be, beginning in late 2015, klean strip + crown changed chemically and are no longer adequate. Hopefully heptane gets the job done.

I have not tried cleaning it, but I have successfully pulled a sizable A/B extraction with the solvent in question. All product was put through re-x with the solvent. The end product was run through mass-spec and found to be clean. Obviously, what ever is causing the vinegar to be cloudy does not translate into the final product via re-x.

It still burned my lips and throat after a re-x and a friend of mine said it was the same for him. I think it may have been something that the company's were experimenting with. I just recently tried some that was perfectly fine. If you look around hard enough you can still find
Klean strip in the old can, that's what i would buy.

As you can see there's a big difference :thumb_up:

Ok, this is POTENTIALLY great news. So would you say mine is ok? The last of my supplies just came in and with a green light, I could proceed today. Just curious: the difference in volume, lighting etc...could my pic being not so cloudy be deceiving?
I ordered heptane which will be here thursday, so I could even do a re X with that if spice is burning after naphtha reX...
