It is a common question that people ask, if a certain chemical is OK to use for extraction or not, and also where to find such and such chemical. Instead of cluttering up the forum with hundreds of threads about it, those who have these question can post here (and threads made with such questions will be merged here).

But before asking such questions, here's a few important links you should THOROUGHLY read:

So I'm very new to the whole DMT community and I've never tried it but have thought about trying an extraction for a while now. I've done a little research here and there and was probably going to try for an ACRB extraction. I work at a car dealership and use non chlorinated brake cleaner almost every day. I haven't seen the full MSDS but on the back of the can it lists Heptane twice with two different CAS numbers and Toluene and Carbon dioxide. It seems to evaporate with no residue at all but I have never really fully tested it. Does this sound like something useful I could use?

Yes it does. Brake cleaner typically has to leave the surface mirror clean with no greasy residue. Bear in mind that the toluene will pull a broader spectrum of things from the bark and will prevent the use of freeze precipitation if it is present in any significant quantity. You are not obliged to use evaporation to recover the goods even though this would be the easiest option. If you back-salt you will be able to reuse your solvent and you'll have better karma for not polluting the atmosphere as much.

Thanks for the quick reply. I'll check out the full MSDS and see if I can find out how much Toluene is in it. It was my first thought because I could easily take some of the cans home and it wouldn't cost me anything.
I don't think I've ever heard of back salting. I'll make a note of it and read up as much as I can.

Hello all, looking for a quick hand assisting a friend I need

He ended up getting best-test rubber cement thinner rather than bestine.

I'm hoping someone can tell me if best test is pure n-heptane or not?

Ty kindly :)

According to what he has told me im.thinking it is not pure heptane. For one, it did dissolve his fats so......

I'm just weighing all possibilities for him. His solution turned an odd color and I'm unsure why. The suspected heptane turned greenish yellow upon adding his crude extract. It also did dissolve his fats and did NOT leave the fats behind

I've told him to get bestine and run a control test to see if it was the best test that did him in. And if not he must have some lye ect left in his crude extract still im.guessing..

I cannot locate best test heptane on the pull down list I checked

Since this event he has gotten bestine. So hoping to salvage here what he can if anything. Thanks for caring

How do you think the $5 Onyx "100%" acetone compares to the $30 reagent-grade stuff?

Update: after requesting their MSDS, it contains Denatonium Benzoate (really bitter) and would likely be difficult to wash out of your final product. It would be fine for things taken orally in a capsule, but while I don't know if it vaporizes, I wouldn't trust it in a smokeable product.

Hi all, finished my first attempt at EW's ACRB tek the other day, which seemed to be successful when I removed from the freezer.

Nice white crystals, though there was a fairly clear waxy coating on the bottom of the bowl which after leaving in front of a fan most of the spice melted into.(the spice on the sides was ok but being a flat bowl most was on the bottom and melted).

I'm hoping this is just plant oils that I didn't clean up properly?

I figured the easiest step would have been to put the naps back in and re-freeze again then when I pull out I could nick off the spice with a blade, before it starts melting, and put in a separate container to dry.

Or I could just re-do the cleanup steps.

But instead I just left the bowl out to evaporate and now I'm left with the waxy substance, still fairly clear with a very slight yellow tinge.

So my question is will all of the naptha evap off this wax if left long enough? Or is it harder to evap 100% when dealing with a wax.

My plan was to leave for another day or so, then add warm iso to melt the waxy substance, then add leaves for changa.

Any help is appreciated.
Acu.

IME scrape, spread, let alone overnight REPEAT. Do this until it begins to solidify. Eventually it will crytsalize. Takes longer than MHRB but if you are patient it will work. Did this for 7 days and I finally got crystals i could chop with the blade into powder. ACRB is more work but I love the result. I suspect something traps solvent. I tend to evap longer than most recommend with any material.

Hi folks! hope everyone has had a great start to the year thus far.

Iw as wondering if anyone knew if this type of toluene was okay to use for a mescaline extraction? click to enlarge picture.

thanks everyone! i sure hope i can use this

I was wondering about Jasco VM&P Naptha. I found an MSDS but it doesn't tell me much other than it's flammable etc. I'm not sure what to look for in regards to it being safe.

I looked up the MSDS for you. It wasn't hard to find with a quick google search. If you scroll down to the "Regulatory Information" section you'll see it says "This material contains Toluene (99% and 100%)", which means it should be fine to use.

Thank you very much for the reply! i Was never quite sure how to figure all this stuff out or exactly what iw as looking for on these sheets. but I have figured it out now :) thanks for your help. it came at the most synchronistic of times!

<=10ppm

Less than or equal to ten parts per million. That sounds like the detection limit of the apparatus used, and considering 0.1% is one thousand parts per million, I'd say that's fairly acceptable for most purposes.

Welcome to the nexus, been here before?

With all this talk of klean-strip having some weird additives now & bestine being out of business i am looking at some new options for solvent.

I appologize if this breaks any rules but i see several places on an auction site or two listing what is labelled as 99%+ purity solvents that appear almost too good to be true. The prices on this stuff is 1/3 or less than most other larger chemical supply companies are charging. It appears to be re-packaged & has some obviously cheap crappy labels stuck on the containers.

I am wondering if this stuff is safe to order & use or whether there is a reason it is so damn cheap & some information is being with-held by the sellers.

I am hesitant to post links/seller names here for obvious reasons.

I'm really sorry to those who've seen these questions in waves, for years, but I didn't satisfactorily resolve this question yet. I'm obtaining the rest of my supplies, and have a question re: my NaOH; the msds for Comstar Pure Lye drain opener said it was 99.9% NaOH. Is this sufficient? Thanks in advance!

I would think so. I just double checked my NaOH and the label reads 98%, so yours is better than mine.

Also, Im hearing ppl say there are now additional additives in vm&p naptha now. Is it still sufficient? Thanks again!

Good question. I tend to go for Swan or Ronsonol myself, but whatever works! Try dripping a tiny drop on to a clean class surface and see if there's any residue after it evaporates, see for yourself
